Just wanted to give another shout-out, this time to a certain popular, hilarious internet cartoon (Flash) known as Strong Bad Email, or sbemails. It's centered around a funny-looking, generally unpleasant bloke typing responses to (real) people's emails with his boxing glove hands (don't ask how he does it...just don't).
These guys have been around for quite a while, but in case you've missed them, here's the link:

I recommend videos like "helium", "personal favorites", "sibbie", "army" and "invisibility". It can take a while to find them in the long list of videos, but it's worth it.
