Mr Mouse is walking through the forest

... when suddenly he hears a loud "HELP! HELP!". He looks around, and there is Mr Elephant, up to his armpits in mud. "What's wrong, Mr Elephant?" says Mr Mouse. "I was walking through the forest, and I got stuck in the mud, and now I can't get out." "Don't worry. I'll be right back" says Mr Mouse. He runs away and comes back 5 minutes later with his Porsche. He throws one end of a rope the elephant, ties the rope to the Porsche, revs it up and just manages to pull Mr Elephant out of the mud. Mr Elephant is ecstatic. "Thank you Mr Mouse" says Mr Elephant, "any time you need a favour, just shout."

Weeks later, Mr Elephant is walking through the forest. Suddenly he hears a high pitched voice calling "Help! Help, Mr Elephant!". He looks around but can't see anybody. "Down here!". He looks down and there is a crack in the forest floor and way down at the bottom is Mr Mouse. "What's up, Mr Mouse?" "I was walking through the forest," says Mr Mouse, "and I fell into this crack in the floor, and now I can't get out". "No problem" says Mr Elephant. He lowers his trunk down in to the crack, but he can't reach Mr Mouse. He checks nobody else is around, whips out his dick, and lowers it down, down in to the crack, and Mr Mouse is able to grab on to it, and gets pulled out of the crack, by Mr Elephant. Moral of the story? If you have a big dick, you don't need a Porsche.
