i saw this as told by robin williams, which i thought was
hilarious.
a man and woman was making love at night when their young son
inadvertantly walked into the room and saw his dad on top on his
mother bopping away. when his parents realized it, it was too
late. with a horrified look, the boy bolted out of
the room.
the father said, "well, honey, i think it is time to tell
little johnny what this is all about."
the wife replied, "yup, you go break it to him gently."
dressed up moments later, the father walked out the
room towards his son's . when he reached there,
little johnny was no where to be found. curious, he
looked around the hallway but was attracted by the sound coming out
from another room.
he walked there and open the room.
he was shocked and horrified when he saw little johhny on top of
his grandmother boning her ragged.
his son then stared at him and said, "now you know how terrible
it feels to see your own mother getting screwed, right!"
