Did you Hear the One?

This ol' blog's been kind of heavy lately. Time to lighten up. Thing is, I'm not too good at jokes.

Here, I'll prove it.

An angel is talking to God. The angel says, "Look, God. I know that you're all-seeing and all-knowing, but for the knock-knock joke to work, you HAVE to say 'Who's there?'"

or

Why did ancient Romans close down the Coliseum?
The lions were eating up the prophets.

Okay, I'll admit. Without Garrison Keillor and Reader's Digest, I got nothin.

How about you? Heard any good ones lately?
