An extremely modest man was in the hospital for a series of tests, the last of which had left his bodily systems extremely upset. Upon making several false alarm trips to the bathroom, he decided the latest episode was another and stayed put. He suddenly filled his bed with diarrhea and was embarrassed beyond his ability to remain rational.
In a complete loss of composure he jumped out of bed, gathered up the bed sheets, and threw them out the hospital window.
Well, it seems that a drunk was walking by the hospital and the sheets landed on him. He started yelling, cursing, and swinging his arms violently trying to get the unknown thing off of him, and ended up with the soiled sheets in a tangled pile at his feet.
As the drunk stood there, unsteady on his feet, staring down at the sheets, a hospital security guard, (barely containing his laughter), and who had watched the whole incident, walked up and asked, "What the heck is going on here?"
The drunk, still staring down replied: "I think I just beat the shit out of a ghost."
