A guy keeps losing weight no matter how much he eats. He goes to the doctor. The doctor examines him and says, "You have a tapeworm."

"Is that a serious problem?"

Doctor says, "No, come back tomorrow and bring an apple and a cookie."

The guy returns the next day with an apple and a cookie.

Doctor says, "Drop your pants and bend over on the examination table."

The guy does so and the doctor quick shoves the apple up his ass. The guy lets out a groan but the doctor tells hm to hold still. About 30 seconds later the doctor shoves the cookie up his ass, to the sound of the man groaning uncomfortably.

"Is that it?", ask the man.

Doctor says, "No, come back again tomorrow with an apple and a cookie."

The guy does this and the uncomfortable process is repeated, first the apple and then 30 seconds later, the cookie.

"Okay, I'm I cured now?"

"No, come back tomorrow. Same deal, bring an apple and a cookie."

And the painful processes plays out for a third day; first the apple and 30 seconds later, the cookie.

"Doc, I can't take this another day."

"Not a problem. Come back tomorrow, but bring an apple and a hammer".

So the guy returns the next day with an apple and a hammer. He drops his pants and the doctor shoves the apple up his ass as before.

About a minute passes...

The tapeworm sticks his head out and says, "Hey! Where's my cookie?"

Doctor takes the hammer and --- WHAAAAMMMM!!!!!!!

"There, you're cured."
