Little Johnny was sitting in his bedroom feeling
really depressed. In walked his dad and asked,
"What's up son?"

Little Johnny replied, "Dad, I really need to get
laid. I'm really horny!"

With that his father pulled $100 from his wallet
and said, "Hear you go son, go in to town tonight
and have a good time."

"Great!" said Little Johnny and off he went.

The next day Little Johnny is in his room feeling
good. In walks his old man again and asks, "How
did you do last night?"

Little Johnny answers, "Hey dad, I got laid last
night and I've still got the $100."

"Wow son, how did you manage that?" his father
asked with interest.

"Well," said Little Johnny, "I went in to town like
you told me and I met grandma there and told her
what I was up to and she took me to her place
and fixed me up".

His fathers jaw dropped and he shouted, "What!
You screwed my mother!?"

Little Johnny said, "why not dad? You screw mine!"
