A construction worker came home just in time to find his wife in bed with another man. So he dragged the man down the stairs to the garage and put his penis in a vice.
He secured it tightly and removed the handle. Then he picked up a hacksaw.

The man, terrified, screamed, "Stop! Stop! You're not going to cut it off, are you?!?"

The husband said, with a horrible gleam of revenge in his eye, "Nope. You are. I'm going to set the garage on fire."
