As a contrast to Saturday's thoughtful, tediously crafted and terribly serious post, here is another Most Excellent Joke™ courtesy of the Junior Ricardipi.*
I've told this one before, but it's an absolute classic, so here it is again.

Who's there?
Monkeysaurus.
Monkeysaurus who?
Monkeysaurus BANANA!!!
[gales of laughter]
Classic, I tell you.
*In this context, the term "most excellent" does not necessarily mean exactly what most people would think it does.
