A man walks into confessional, desperate to relieve his guilt.
"Bless me, Father, for I have sinned."
"Yes, my son. Confess your sins."
"Well, Father, I'm afraid I've killed my wife!" admits the man.
"That's terrible, my son!" the horrified priest gasps. "How did this happen? Why would you commit such a crime?"
"Well, Father, I decided to surprise my wife by coming home early from work, and when I walked up the stairs to our bedroom, I could hear moaning. I crept up the rest of the way, and I was shocked to see my wife and my best friend, Sam, in bed together! They were rolling about, naked and obviously in the throes of sex!"
"Oh, my goodness!"
"Yes, Father. So I just lost my mind with jealousy! I grabbed my gun, burst into our bedroom, and shot my wife!"
"Oh, that's terrible! Terrible, my son! What did you do to your best friend, Sam, after that?"
"What else could I do? I gave him a smack on the nose and yelled, 'Bad dog!'"
