Kidnapped

Listen up, buttercup. The joke is a pun using "Iran" and "I ran." Get it? The dude got kidnapped in Iran, but he escaped, so "luckily, I ran." It's funny 'cause it sounds the same, and you're supposed to be surprised. You probably thought he was gonna say somethin' bad about Iran, huh? Bet you also think ketchup is a vegetable.
