A joke about childbirth...

Little Johnny was assigned a paper on childbirth and asked his mother,
"How was I born?" "The stork brought you to us." "Oh," said Little Johnny.
"Well, how did you and daddy get born?" he asked. "Oh, the stork brought
us too." "So. . . how were grandpa and grandma born?" "Well, darling, the
stork brought them too," said the mother. The next day Little Johnny
handed in his paper to the teacher. It read, "This report is impossible to
write due to the fact that there hasn't been a natural childbirth in my
family for three generations."
