A mouse and a lion walk were in a bar, drinking a few beers when a
   giraffe walked in.
   "Get a load of her" said the mouse, "what a babe!" "Well, why not try
   your luck?" replied
   the lion. So the mouse went over to the giraffe and started talking to
   her. Within five
   minutes they're out the door and into the night. The next day, the
   lion was drinking in the
   bar, when the mouse staggered in. The mouse is completely worn out,
   and can hardly hold
   himself up. The lion helped his pal up on to a stool, poured a drink
   down his throat and
   said, "What the hell happened to you? I saw you leave with the
   giraffe, what happened
   after that? Was she all right?"
   The mouse replied, "Yeah, she was really something, we went out to
   dinner, had a couple
   of glasses of wine, and she invited me back to her place to spend the
   night. And oh, man!
   I've never had a night like it!" "But how come you look like you're so
   exhausted?" asked
   the lion. "Well" said the mouse, "between the kissing and the
   screwing, I must have run a
   thousand miles!"
