Ever been talking to somebody when they try to convince you of the most outrageous thing? They're bald-faced lying and you know they're lying, but they keep bs-ing you. What's the stupidest/wildest thing someone's ever tried to convince you of?

Here's two lousy examples:

1) My cousin telling me "gullible" isn't in the dictionary. (I almost looked, but caught myself just in time. The pretty girl walking down the street distracted me, dangit!)
2) A guy tried to tell me that Linkin Park and Metallica teamed up to do remixes of "Salt Shaker", "Get Low", and "In Da Club". I wasn't sure whether to hit him for insulting my intelligence like that or laugh in his face. :rolleyes2
