The comments to Beck's rant at one of my favorite science blogs, Pharyngula, are worth a read:
"I haven't seen a half-monkey half-person yet"
So Glenn Beck hasn't been to a Glenn Beck fan gathering?
He's right! Evolution clearly posits half-man half-monkeys. And crocoducks. Ever seen one? Ever seen a horse fly? Or a barn dance? I once shot an elephant in my pajamas. How he got into my pajamas, science cannot explain.
Whenever I hear someone talk well of Glenn Beck or Sarah Palin in casual conversation, it's like glancing at a dead canary... I know it's time to get the hell away from the mine.
and one more:
Could he really believe that everyone was thinking the world was flat, then as soon as someone said otherwise everyone said "ok that sounds good." I guess he believes whatever random thought occurs to him.
