A mother & father take their son to the Zoo.

While standing at the elephant enclosure enclosure a bull elephant produces a huge erection.

The young lad shouts : Mommy, whats that big thing hanging down? All the people around her are laughing & she is very embarrassed.

Mother: Hush now, thats his trunk.

Boy: (Loudly) No, No mommy. The OTHER big thing!

Mom. Thats nothing, nothing, now go get you father.

He runs over to his father and, of course he asks "what's that Dad?"

Father: Well son, that's the elephant's PENIS.

I asked Ma & she said "that;s Nothing!"
Dad: That bloody woman, NEVER Fuckin, Satisfied!
