I'd Rather Have a Puppy.

Little Johnny is walking with his father in the park and they see two dogs locked in a sexual embrace. Little Johnny not understanding what the dogs are doing asks his father, "Daddy, what are those two dogs doing?" To which the father replies, "They are making a puppy!" Later that night Johnny wakes up and walks down the hall to his parents bedroom and catches his mother and father making love. Johnny asks his father, "Daddy what are you and mommy doing?" To which the father replies, "Johnny we are making you a little sister." Johnny thinks for a few moments and responds, "Well, daddy could you roll her over? I'd rather have a puppy!"

Little Billy - Fascinated

A teacher asked her students to use the word "fascinate" in a sentence. Mary said, "My family went to the New York City Zoo, and we saw all the animals. It was fascinating." The teacher said, "That was good, but I wanted the word 'fascinate.'" Sally raised her hand. She said, "My family went to the Philadelphia Zoo and saw the animals. I was fascinated." The teacher said, "Good, but I still want the word 'fascinate.'"
Little Billy raised his hand. The teacher hesitated because Billy was noted for his bad language. She finally decided there was no way he could damage the word "fascinate" so she called on him. Billy said, "My sister has a sweater with 10 buttons, but her boobs are so big she can only fasten 8!"

Nickels and Dimes

Little Johnny is always being teased by the other neighborhood boys for being stupid. Their favorite joke is to offer Johnny his choice between a nickel and a dime -- Little Johnny always takes the nickel. One day, after Johnny takes the nickel, a neighbor man takes him aside and says, "Johnny, those boys are making fun of you. Don't you know that a dime is worth more than a nickel, even though the nickel's bigger?" Johnny grins and says, "Well, if I took the dime, they'd stop doing it, and so far I've made $20!"
