One of my old jokes

A group of guys visiting the Zoo one day & they decide to do a dare. Whoever draws the short straw has to streak past the animal cages, so they draw straws & the loser streaks past the Lion cage stops & shakes his hips the male Lion roars he then goes to the Elephant cage where two Elephants are standing in a pool watching life goe by, he stands in front of the cage & shakes his hips at them then he hears a Warden shout OY so he runs off chased by the Warden after they have gone one of the Elephants puts his trunk into the water & then sprays the water over his back then he turns to his mate & says 'how the hell does he manage to wash himself with that'
