Beyond April 1st: While connected to April Fool’s, these idioms apply year-round to any situation involving jokes, tricks, or deception.
Idiom #1: Pull Someone’s Leg
Meaning: To joke with someone by telling them something that isn’t true; to tease someone playfully; to trick someone as a joke (not maliciously).
Origin: The exact origin is disputed. One theory suggests pickpockets in Victorian England would literally pull victims’ legs to trip them during robbery. Metaphorically, “pulling someone’s leg” became tricking them in a playful, non-harmful way—like an April Fool’s prank.
How to use it:
“Are you serious, or are you just pulling my leg?” “I can’t tell if you’re pulling my leg or telling the truth.” “He told me I won the lottery, but he was just pulling my leg.”
Grammar note: “Pull someone’s leg” (present), “pulled his/her/their leg” (past). Always use possessive before “leg” (my/your/his/her/their leg).
Real-life examples:
Friendly teasing: “My coworker told me the boss wanted to see me urgently. I panicked until I realized she was just pulling my leg—there was no meeting.”
Uncertain about truth: “When he said he’d met the president, I thought he was pulling my leg. But he showed me the photo!”
Admitting a joke: “I’m sorry—I was just pulling your leg. The meeting isn’t canceled. I was joking around.”
Testing credibility: “You’re telling me you’ve never heard of pizza? Come on, you must be pulling my leg!”
April Fool’s context: “On April 1st, everyone is pulling everyone’s leg—you can’t trust anything anyone says!”
Between friends: “My friend told me my favorite restaurant closed. When I got upset, he admitted he was pulling my leg.”
When to use this idiom:
Describes playful, non-harmful jokes or teasing. NOT for:
- Serious deception or fraud
- Malicious lies
- Harmful tricks
Tone: Lighthearted, playful, friendly. Implies harmless fun.
Variations:
“Just kidding” (shorter, direct way to reveal a joke) “I’m moving to Antarctica—just kidding!”
“I’m only joking” (similar meaning) “You looked so worried! I’m only joking—everything’s fine.”
Related expressions:
“Yank someone’s chain” (American version of pulling leg) “He’s yanking your chain—don’t believe him.”
“Have someone on” (British—playfully deceive) “Are you having me on, or is that true?”
Common mistakes:
❌ “Pull your foot” (wrong body part) âś“ “Pull your leg”
❌ “Pull the leg” (missing possessive) âś“ “Pull someone’s leg” / “Pull your leg”
Professional context: Generally avoid in formal professional settings. Save for casual conversations with colleagues you know well.
Cultural note: This is one of the most common English idioms. Even non-native speakers often recognize it.
Idiom #2: Fall For (Something/Someone)
Meaning: To be deceived by something; to believe something false; to be tricked; to accept something as true when it isn’t.
Note: “Fall for someone” has a different meaning (develop romantic feelings), but “fall for something” means being deceived.
Origin: “Fall” metaphorically represents being brought down or losing one’s footing—losing stability by believing something false.
How to use it:
“I can’t believe I fell for that prank!” “She fell for the fake news story.” “Don’t fall for his lies.”
Grammar note: “Fall for something” (present), “fell for it” (past), “fallen for the trick” (present perfect). Object is always the deception/trick.
Real-life examples:
April Fool’s prank: “My roommate told me classes were canceled. I fell for it completely and went back to bed. Then I realized it was April 1st!”
Advertising tricks: “The ad promised miracle weight loss. I fell for it and bought the product—it didn’t work at all.”
Scams: “He fell for an email scam and gave away his password. Now his account is hacked.”
Fake news: “Many people fell for the fake story about celebrities. They shared it on social media without checking.”
Magic tricks: “The magician’s trick was so good—everyone in the audience fell for it. We couldn’t figure out how he did it.”
Practical jokes: “My brother put salt in the sugar bowl. When I made coffee, I fell for it and ruined my drink!”
Why this idiom matters:
Common in discussions about:
- Pranks and jokes
- Scams and fraud
- Misleading information
- Gullibility
- Deceptive appearances
Tone: Can be self-deprecating (admitting your mistake), warning (cautioning others), or critical (suggesting someone is gullible).

“Buy into” (accept something false) “I can’t believe she bought into that conspiracy theory.”
Related expressions:
“Hook, line, and sinker” (completely deceived, from fishing) “He fell for the lie hook, line, and sinker—believed every word.”
“Swallow the story” (believe something unlikely) “She swallowed the whole story without questioning it.”
Common mistakes:
❌ “Fall for it” when meaning romance (confusing meanings) Context matters: “I fell for him” = romance; “I fell for it” = deception
❌ “Fall to something” (wrong preposition) âś“ “Fall for something”
Professional context: “Don’t fall for the competitor’s misleading claims about their product—check the actual data.”
Idiom #3: The Joke’s On (Someone)
Meaning: The person who thought they were tricking someone else ends up being the one who looks foolish; the situation backfires on the joker; unexpected reversal where the trickster becomes the victim of their own joke.

Common Mistakes ESL Learners Make
Understanding typical errors prevents them.
Mistake #1: Confusing “Fall For” Meanings
Problem: “Fall for” means deception OR romance depending on object.
Deception: “I fell for the prank” âś“ Romance: “I fell for him” âś“ Confused: “I fell for it” when meaning romance âś—
Solution: Object determines meaning—”it/that/trick” = deception; “him/her” = romance.
Mistake #2: Wrong Prepositions
Wrong: “Pull someone’s foot” / “Play a trick to someone” / “Take by a grain” Right: “Pull someone’s leg” / “Play a trick on someone” / “Take with a grain”
Solution: These are fixed expressions—prepositions cannot change.
Mistake #3: Literal Interpretation
Problem: Taking idioms literally creates confusion.
Example: “Pull someone’s leg” doesn’t involve touching legs.
Solution: Remember these are metaphors about jokes and deception—not physical actions.
Mistake #4: Using Playful Idioms in Serious Contexts
Problem: “Pull someone’s leg” sounds inappropriate for serious fraud.
Wrong: “The company pulled investors’ legs about their finances.” (too playful for serious fraud) Right: “The company deceived investors about their finances.”
Solution: Match idiom tone to situation severity.
Mistake #5: Forgetting Articles
Wrong: “Make fool of yourself” / “Take with grain of salt” Right: “Make a fool of yourself” / “Take with a grain of salt”
Solution: These expressions require specific articles—”a fool,” “a grain.”
