Here's a clip of Dennis Miller from all the way back in 1990. Be forewarned, as is common with Miller's style, there is an abundance of NSFW language:
I've always been a fan of Miller even though he's been labelled as a conservative and supports John McCain (though he's pro-choice and supports gay marriage). It's nice to see him taking potshots at religion.
Best line: "They say they don't favour any particular denomination but I think we've all seen their eyes light up at 10s and 20s."
