This is one of the best ones I have heard. I am just telling by memory so if I misquote or don’t tell it quite right I apologize. Basically it goes:
A zoo keeper had an elephant that seemed to be having a problem…er…was backed up, I guess you could say. The zoo keeper gave the elephant laxatives for a few days with no apparent result. He then decided to give the elephant an enema. Then enema worked, very well in fact. The unfortunate zoo keeper was buried under
and suffocated by a very large pile or elephant dung.
