A mouse was making his way though a forest when he came across an elephant pinned to the ground by a rotting tree branch which had fallen on its trunk - it had been there for several days and was in a pretty bad way.
The mouse set-to with a vengeance, scraping and burrowing under the branch for a long-long time, until at last, the elephant was able to drag itself free.
Overcome with gratitude, the elephant profusely thanked the mouse and told him that anything it could possibly do in return, it was there for the asking.
The mouse looked a little embarrassed, and finally said; "to tell you the truth, as stupid as it may sound, I've always wanted to make love to an elephant".   
"No problem", says the elephant.
So they sat down, worked out how it was going to be done, and made a start.
They hadn't been at it for a minute or so, when another huge rotten tree branch broke and smacked the elephant squarely across the head - she let out a might roar.
"I'm sorry", said the mouse, "was I being too rough?"
