Courtesy of Da Goddess. She has a list of exchanges from its vintage days that it would be a shame to miss.
But I promised Adult Elephant Jokes, so here goes (The answers came from Paul Lynde).
"Can you get an elephant drunk?" "Sure, but he won't go up to your apartment"
"Who stays pregnant for a longer period of time, your wife or your elephant?" "Who told you about my elephant?"
(Actually I don't think he had a wife either).
