Tapeworm

A guy goes into a doctor office and says, "I think I have a
tapeworm, doctor. I keep eating and eating but I don't gain any
weight!" The doctor says, "Come see me tomorrow, and bring a
banana, and a cookie."


So the man buys a banana and a cookie on the way home, and goes
to the doctor the next day. The doctor says to him, "Okay, give
me the banana and the cookie, and pull down your pants." "Are
you sure?" "Positive." Grudgingly, he pulls down his pants. The
doctor shoves the banana right up his ass. He waits a few
minutes, and up goes the cookie.


The doctor says, "Okay, now tomorrow, I want you to do the same
thing." So he does. And this goes on for about a week.


On the second to last day, after treatment, the doctor says,
"For tomorrow, I want you to bring a banana and a hammer."
Fearing the worst, but wanting to get rid of the tapeworm, the
man does so.


The next day, up goes the banana. The doctor waits a few
minutes, and then out pops a sign that says, "Hey! where's my
cookie?!" And well, I think you can figure out what the doctor
did with the hammer.
