I Have This And You Don't

Little Johnny and Mary are in the backyard.

Johnny says: "My dad's got a brand new Cadillac"

"Big deal, my daddy has a brand new BMW" says Mary.

"Well, my daddy has a brand new 6 foot swimming pool" says Johnny.

"Big deal, my daddy has a brand new 12 foot swimming pool" Mary says.

Well this goes on for quite some time and Johnny is really getting upset so finally he pulls down his pants and says "Well I got one of these and my daddy says you don't".

So Mary hikes up her skirt and says .....

"Well, my mommy says that I have one of these, and with one of these I can get as many of those that I want."
