Here's a funny animation I caught on Pharyngula, the excellent science blog by P.Z. Myers.  The audio is German, but there are subtitles.  I got a kick out of it, perhaps you will too?

Das Rad

Friends and readers, ULev has acquired its own troll.  I should feel flattered I guess, but this coward is such a scumbag he's not above leaving anonymous comments insulting my daughter.  What does this mean for everyone else?  From now on once you post a comment it will be sent to me for moderation.  This means it will not appear on the blog until I approve it.  I apologize for the delay.  Thank the asshole.
