A fellow went to his doctor complaining that his asshole was feeling terribly sore.

The doctor asked him to drop his drawers and bend over so he could take a look.

"This is amazing!" the doctor said, as he pulled a $20 bill from the fellow's anus.

Another $20 bill appeared behind the first one, so the doctor pulled it out, too.

And then another! And another! And many many more. 

Finally, the doctor had pulled the last $20 from the guys ass. 

He looked at the large pile of $20 bills on his desk, and began to count them. (I sure hope that the doctor doesn't lick his thumb when he counts money)

Finally the doc exclaimed, "There was $1,980 stuck in your ass!"

And the fellow replied, "I knew I wasn't feeling two grand!"
