Dirty sheet

 A man was in the hospital around Halloween, for a series of test which had left his bodily system extremely upset. after a few false alarm trips to the bathroom he decided to just stay in bed...He suddenly had a big accident, Embarrassed beyond his ability to remain rational. In a complete loss of composure, he jumped out of bed, ripped the bed sheet off the bed and threw it out the hospital window.

A drunk was walking by when the sheet landed on him. He started yelling, cursing and swinging his arms violently trying to get this unknown thing off of him and ended up with the dirty sheet in a tangled pile at his feet.

As the drunk stood there staring down at the sheet, a hospital security guard walked up and asked

"What the hell is going on"?

The drunk still staring down replied

"I just think I just beat the crap out of a ghost"
