“What do you get when an cross an elephant with a RINO?” (joke)

A joke cited in print from at least 1973 is:
 
Q. What do you get when you cross an elephant with a rhino.
A. An elephino. (Hell-if-I-know—ed.)
 
The joke is also told with RINO (Republican In Name Only). An elephant is a Republican party symbol. “What do you get when you cross an elephant with a RINO?” was told in September 2008; the answer was John McCain, the Republican presidential candidate.

What do you get when you cross an elephant with a RINO?
(Illustration shows “McCAIN 2008.”—ed.)
As they say, a picture is worth a thousand words.  But I’ll give you a little help understanding this one.  “RINO” is a news junkie acronym meaning “Republican in name only”.  The elephant is the mascot of the Republican party.  Talk amongst yourselves…

That was funny when I was a kid, but it’s especially funny now given Republican politics (elephant being the symbol of the party, RINO being the new term for moderate Republicans). I’m going to start saying “elephino” when people ask what party I belong to 😊
