Video clips that amuse and make me laugh

I have been checking out some YouTube clips. These two are rather witty songs by The Richter Scales - a clever name for a singing group. See their blog. (Both of these preceding links seem to be having connection problems at the time of writing though.)
Check it:

• Stockholm Syndrome
• Here Comes Another Bubble

If, however, you might like something more provocative, then you could do worse than check out some of the 30 (and counting) vid clips from this articulate and prolific YouTube user - an English guy called Pat Condell. He takes to task the Americans, the Muslims, the Christians, and more. He's a very witty iconoclast, and I think he displays some good critical thinking skills too. We could probably all learn from this guy to be a little more reflective regarding our own beliefs and bias.
Amongst my favourites are:

• Laugh at Sudan (for scoring a superb "own goal" over the amazingly stupid Muhammad-teddy-bear-naming-insult saga)
• The trouble with Islam
• United States of Jesus
• Catholic morality
  

- and this one is very good, imho: A word to Islamofascists (look out all Islamofascists and white supremacists).
