I walked in on the old man who was the founder and prez of a steel company we shared the floor with, attempting to crap in the urinal. When I walked in he said... "Oh, I can't do this here." and went into one of the stalls (pants still down).
He was really rough ridin' senile so it was more sad than funny at the time. But now, I think it's funny as crap so I posted it in this thread.
