Q: How do you make
four old ladies say "FUCK!"?

One day a construction worker left the job a little early, and when he got home he found his wife in bed with another man. Purple with rage, he hauled the man down the stairs and into the garage where he proceeded to secure his dick in a vice.
Utterly terrified, the man screamed, "Stop, stop! you're not going to cut it off, are you? ARE YOU?"
"Nope," replied the construction worker, "You are...I'm going to set the garage on fire."
