In a similar vein, a dude in a pub bets $100 with a stranger that he can bite his right eye. As you guessed, fake eye comes out and goes gently between the teeth, bet won. He then offers double or nothing that he can bite his left eye. Stranger notes that this weirdo clearly has some vision, and figures he can't have two fake eyes, so lays the bet. False teeth out, gently clamped on left eye. Come in sucker!
