Little Johnny is visiting the zoo with his mother. They go to the
elephant exhibit, where a big old bull elephant is taking a leak. Johnny
points to the pachyderms privates and says, Mommy, whats that? Mommy,
seeing the huge member, turns bright red and says, Oh, thats nothing.
Never mind. Come along now.

A few weeks later, Johnny is at the zoo with his father. Johnny grabs his
dad by the hand, and pulls him over the elephants, saying he has a
question. Once there, Johnny points to the elephants member and says,
Daddy, whats that? Dad replies, Didnt your mother tell you? Yes,
she told me it was nothing. Well, your mom is spoiled, son.
