"In the beginning there was nothing. God said, 'Let there be light!' And there was light. There was still nothing, but you could see it a whole lot better." --Ellen DeGeneres

Official Timesink Warning: If you've got some time to kill, check out GraphJam for a few good laughs. People submit graphs they have to explain pop culture ideas, everything from song lyrics to movie & TV plots to cliches. Some of them are quite funny.
So far, my favorites are Parental IQ versus Child’s Age, The United States According To Network Executives and words that Rhyme With Texas, but I'm only on page 4 so far.
Oh - and if they don't make sense, look at the Cheat Sheet if one's available for that graph.
