LOL!
I don't know much about MGS, but it was still funny.
My favourite parts were:
When Snake is about to climb a ladder, then gets a call from the Colonel, rips out his ear and shouts "Shut up I know how to climb a goddamn ladder!"
AND...
At the beginning, that girl with the red hair's voice (don't know her name) and she's like "HELLOSOLID SNAAAAAAAKE!"
Good work, if it's funny for someone who isn't a fan of MGS, then it must be great for MGS fans!
