A little boy and a little girl, on a beach, are arguing. Little boy says to the little girl, I have a Nintendo!

Little girl says, Oh yeah, well I have a Sega and a Nintendo!

Little boy says, So, my dads a doctor!

Little girls says, My dads an astronaut!

Back and forth they went, each one trying to outdo the other until finally the little boy pulls down his shorts and proclaims, But I have on of these!!!! and shows the little girl his penis.

The little girl, not being able to retaliate, gets up and goes home. The next day, the little girl spots the little boy and proudly announces, My mom said that with one of these (pointing to hers) I can get as many of those as I want!!!!!!
