A father comes home and asks where his son is. His wife
replies that
he's downstairs playing with his new chemistry set. The
father is
curious so he wanders down stairs to see what his son is
doing. As
he's walking down the steps he hears a banging sound.
When he gets to
the bottom he sees his son pounding a nail into the wall.
He says to
his son, "What are you doing? I thought you were playing
with your
chemistry set. Why are you hammering a nail into the
wall?" His son
replied, "This isn't a nail, dad, it's a worm. I put
these chemicals
on it and it became hard as a rock."
His dad thought about it for a minute and said, "I'll tell
you what
son, give me those chemicals and I'll give you a new
Volkswagon." His
son quite naturally said, "Sure why not."
The next day his son went into the garage to see his new
car. Parked
in the garage was a brand new Mercedes. Just then his dad
walked in.
He asked his father where his Volkswagon was. His dad
replied, "It's
right there behind the Mercedes. By the way, the Mercedes
is from your
mother."
