Dick into a vice
A man arrives home one evening and found his wife in bed with another man. The husband grabbed the offending man by his nob and dragged him to the garage.
After putting his dick into a vice and removing the key so it couldn't be loosened he walked over to the bench and took a saw off the hanger.
The naked man said, "My god you are not going to cut it off?"
The husband replied, "Oh no sir, this is for you. I am going to set fire to the garage and leave. What you do next is your decision.
