Here’s a couple of absolutely brilliant sketches from a UK TV show called That Mitchell and Webb Look.  Both sketches are from S03E04.  I think I’m going to have to look in to this show a bit more.

The second one you have to be a little careful of.  I think I may have woken the entire block of units I live in from laughing so hard at the final line.

Both video’s found via P.Z. Myers’ website Pharyngula.
