A man walks into a bar has a few
drinks and asks what his tab was. The bartender replies that it is
twenty dollars plus tip. The guy says, "I'll bet you my tab double or
nothing that I can bite my eye." The bartender accepts the bet, and the
guy pulls out his glass eye and bites it.
He has a few more drinks and asks for his bill again. The bartender
reports that his bill now is thirty dollars plus tip. He bets the
bartender he can bite his other eye. The bartender accepts knowing the
man can't possibly have two glass eyes. The guy then proceeds by taking
out his false teeth and biting his other eye.
