One night, a young boy heard noises from his parent's bedroom.
It was hard for him, but he went back to sleep. The next night
he heard the same noises, but once again fell back asleep.
Finally, on the third day that he was woken up by his parents,
he decides to see what the heck they are doing.
So he walks up to his parents room, and sees his mother on top
of his father. She is moving up and down on top of him, and they
both are making grunting noises. He has no idea what is going
on, and decides to go back to bed.
The next morning the boy tells his mother about how they woke
him up, and what he saw when he went to see what they were
doing. Finally, he asks what was going on. His mother decides he
is too young to learn about sex, so she tells him that since his
father is getting old and fat, she has to jump on top on him to
keep him thin.
"But mommy," the boy exclaims, "That won't work, cause everyday
when you go to work, the next door neighboor comes over and
blows him back up!"
