A cop sees Little Johnny standing on a street corner. He goes up to him and says "What are you doing here?"
Little Johnny replies " I'm looking for a whore."
"Why are you doing that?"
Johnny replies "Cause I want an STD."
The cop asks "Do you know what that is?"
"Ya, it's a sexually transmitted disease."
"OK" the cop said," Why do what that?"
"So I can give it to my baby sitter."
"Why is that?"
"So she can give it to my dad."
The puzzled cop asked "Why?"
"So he can give it to my mom."
Looking more confused and puzzled the cop again asked "Why?"
"So she can give it to the gardener, cause that's the B%stard that kill my frog."
