I found this gem mine in youtube - Freeman's Mind. Created by Ross Scott

It follows the thoughts of Dr. Gordon Freeman (As he doesn't speak throughout the game), a 27 year old physicist and neurotic individual. It is a humorous playthrough of the game where the author solloqualizes as Gordon Freeman in a most funny way. Here's Ep. 3 (For example). https://www.youtube.com/watch?v=63S3...C3B7EDD1624C55

I vividly recommend it for anyone who has played Half Life. :D It is awesome.
