Little Johnny Stories - I Like Your Thinking

Little Johnny and his Dad have to move to a seedy neighborhood after the divorce, Johnny's in the back yard playing. He notices men going in a door across the street, and when they come out they have a big smile on their face.
After a week or so he asks "Dad, what the hell they sellin' over there that makes all them fellers so happy?"
His Dad looks the place over and says "Never you mind boy. You're too young for such as that."
Another week or so goes by and curiosity gets the best of him. He goes and breaks his piggy bank, takes the 37 cents and runs across the street.
He walks up to the counter and sees a woman with huge boobs sitting behind it.
He says "Ma'am, I wanna buy 37 cents worth 'o whatever it is you got in here that's makin' all them fellers grin so much."
The Madam looks at Johnny, smiles and reaches between her legs, then reaches over the counter and runs her finger under his nose.

Johnny wrinkles his face and yells "Sonofabitch! Glad I didn't buy no dollars worth!"
