Spy

The class in Team Fortress 2 that everyone hates, but everyone plays as. Seriously, playing Spy will take your soul. If you actually want to help your team win, you play as Heavy, Medic, or Soldier, NOT Spy!

French man in a suit and ski mask, who runs around backstabbing people and fucking your mother

Hands down, the most fun class in Team Fortress 2. Among being able to disguise himself as a member of the other team, He can also turn invisable, and is very skilled in the art of having sex with your mom. The Spy is equipped with a knife that when stabbed into the back of some Sniper mother fucker (or anyone for that matter), kills them instantly. The Spy also has a quite powerful revolver known as the Ambassador, that can distribute a great deal of damage when shot in the head. The Spy has a tiny machine called an electro sapper which can disable any "building" created by an Engineer.
