Did you know that if you stick two Peeps in the microwave, and then stick toothpicks in the Peeps such that the toothpicks form a cross when the Peeps face each other, you can get the Peeps to sword fight by turning on the microwave?
^ Oh. That may be useful. If I make some bussiness with the devil and he demands that, as the payment, I fight in a sword duel to the death (loser's soul goes to the devil), I'll trick him by promising a sword fight where _both_ fighters are dead by the end. Then show him dueling Peeps.
