1. Responding to a joke or prank:
* "You're pulling my leg, right? You can't seriously be telling me you ate the whole cake!"
* "Don't pull my leg! You're not really going to skydive, are you?"
2. Accusing someone of lying or exaggerating:
* "I think you're pulling my leg about winning the lottery. You're always joking around."
* "Come on, you're pulling my leg! You didn't actually climb Mount Everest, did you?"
3. Expressing skepticism or disbelief:
* "You're pulling my leg, I know you are. There's no way I got a perfect score on the test."
* "You're telling me you saw a unicorn in your backyard? You're pulling my leg, right?"
4. Emphasizing the absurdity of a situation:
* "They're saying they're going to build a giant robot? They must be pulling my leg!"
* "You're pulling my leg, I know you are! That's the most ridiculous thing I've ever heard!"
5. Using it in a lighthearted way:
* "I'm just pulling your leg, don't worry. I was just trying to get a rise out of you."
* "I'm not pulling your leg. I'm serious!" (used when you really are telling the truth)
Remember, the tone of the idiom is usually lighthearted and playful, even when accusing someone of lying. It suggests that you don't believe the person is being serious, but that you are not offended by their joke or prank.
