Simon's Cat.  This cartoon makes me laugh out loud every time I've seen it...and I've seen it way too many times.

Anyone who has a cat can identify with this short video.  Cats don't believe anyone should be sleeping if they are awake.  Of course if they are asleep they don't want to be disturbed, but if you are sleeping...who cares.

Check out how Simon's Cat wakes his unsuspecting owner.  Hee Hee Hee.
