When you piss into an unraveled condom and tie it off, put it in the freezer, and wait 4 to 6 hours. When you return, it should be frozen. then, you invite a sister or cousin over, drug her, and stick it inside her using baby oil as lubricant.
A rare mishap which occurs during an after dinner wank.
When wanking you notice a rather significant sensation. It may be intensely painful or pleasantly warm, hot even.
You worry for a moment and even panic as it feels as though your sausage is being cooked. You look at your hands which appear clean. After a moment it clicks. You put two and two together.
Your meal was rather spicy, containing large amounts of high potency chilli sauce. Some must have gotten on your hands.
Dave: Steve, come down and check this out!

Steve: I can't, I've got a severe case of chilli willy.
Steve: *limps down the corridor*
Dave: What's happened? Did you get hit in the balls?
Steve: No, I've got chilli willy you silly willy.
