A couple of classic comedy sketches I've been thinking about lately.
Rowan Atkinson as an alien with communication issues. (Well, I say "no reason", but I was reminded of this by some of the bird noises in Angry Birds. Yes, seriously. I may need help...)
And The Two Ronnies Mastermind sketch. Cracks me up every time. (Sorry, sound on this one is a bit loud, you may need to turn it down a notch or two. Or risk annoying/amusing the neighbours. TMMV.)
