An extremely modest man was in the hospital for a series of tests, the last of which had left his system upset. Upon making several false-alarm trips to the bathroom, he decided the latest was another, and stayed put.

He suddenly filled his bed with diarrhea and was embarrassed beyond his ability to remain rational. Losing his presence of mind, he jumped up, gathered up the bed sheets, and threw them out the hospital window.

A drunk was walking by the hospital when the sheets landed on him.
He started yelling, cursing, and swinging his arms wildly, which left the soiled sheets in a tangled pile at his feet.

As the drunk stood there staring down at the sheets, a security guard, who had watched the whole incident, walked up and asked, "What the hell was that all about?"

Still staring down, the drunk replied, "I think I just beat the crap out of a ghost!"
