00:00Place a grape on the bar and cover it with a hat.
00:03Then bet your friend $100 that you can eat the grape without touching the hat.
00:10Now, it seems impossible, so he'll probably agree to the bet.
00:15Then all you have to do is pretend that you're eating the grape and tell him to pay up.
00:21He'll look confused, but you should insist that he pays because he lost the bet.
00:28At which point, he'll pick up the hat, see the grape, and laugh in your face.
00:33And that's when you actually eat the grape.
