A man goes home early and catches another man in bed with his wife.
He drags the naked man out of the house and into his garden shed.
There he secures man's penis in a vice and removes the handle, then starts to sharpen a knife.
The naked man shouts, "You're not going to cut it off are you?"
"No, you are," was the reply.  "I'm going to set fire to the shed"
