...Mother Russia, biznatches.
Rule No 1 of war: Don't invade Russia.
Rule No 2 of war: Really, don't invade Russia.
Rule No 3 of war: Really, seriously, don't fucking invade Russia.
Rule No 4 of war: Trenches suck.
Rule No 5 of war: Know thy enemy.
Rule No 6 of war: Don't invade Russia, you dipshits. They will take your mother's bones and shove them up your rectum so far that you can taste them. I once knew a guy who tried to invade Russia, and his skin was flayed off by a thousand bearded men riding bears. Then they looked through his wallet, found the address of his country farm, killed his family, sheared his sheep, took all of his potatoes for vodka, and then pissed on his carrots. His carrots were instantly blighted with plague, which spread throughout the land and killed everyone he had ever known, by making them go insane and invade their earholes with rich tea biscuits. After they had done that, they rode home drunk on bears, killed an old lady and a girl guides group, and did a Cossack dance on their graves.
