Immediately the bartender notices that this man stinks.  In fact, he reeks, and the bartender asks the man why he stinks.

"You see" the patron replied, "It's my job to take care of the elephants (okay, donkeys?) in the circus.  And sometimes they get constipated, and we have to flush them out with a hose.  And sometimes, like today, I just don't get out of the way before things happen."

The bartender is horrified.  "Why don't you get a better job?" the bartender asks.  

"What, and give up show business???" was patron's response....
