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 figured that
 the  latest episode was just that, so he stayed put.

 Suddenly, however, he 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.

 A drunk was walking by the hospital when the sheets landed on him. The
 drunk started yelling, cursing, and swinging his arms
violently, in an attempt
 to free himself of the sheets.

 He ended up with the soiled sheets in a tangled pile at his feet.

 As the drunk stood there, staring down at the sheets, a hospital
security guard who had witnessed the entire incident,
walked up to him and asked,

 "What the heck is going on?"

 The drunk, still staring down at the sheets, replied, "I think I just
 beat
 the crap out of a ghost."
