Meet the Demoman is the best.
Demoman: "I got a manky eye. I'm a black, Scottish cyclops. They've got more [humorously long censor bleep] ...than they've got the likes of me."
[The Demoman starts to drink from the empty bottle, then notices the camera and becomes lucid again]
[Bagpipes start to play in the background]
Demoman: "....T'all you fine dandies so proud, so cock-sure."
[The Demoman runs out to the final capture point in Gravelpit and is shocked to see a group of BLU team members charging towards him with smug expressions on their faces. A devious look comes over the Demoman's face and he runs with BLU in hot pursuit]
Demoman: "Prancin' aboot with your heads full of eyeballs! Come and get me I say. [The Demoman covers a door frame in sticky bombs] I'll be waiting on ya with a whiff of the 'ol brimstone. I'm a grim bloody fable....with an unhappy bloody end!"
[The Heavy notices the sticky bombs around the door frame, and his expression changes from smug to one of shock. The Demoman throws a mock salute and activates the sticky bombs, gibbing all his pursuers]
[The Demoman walks up to (presumably) a decapitated head, laughing merrily as body parts and blood rain down around him.]
Demoman: "Oh, they're going to have to glue you back together....in hell!"
Monster - :3 I just like fucking with your brain meats.
Chocolate Hurricane - Never thought I'd agree with him.
Omicron - Even though everyone seems to hate flesh, gotta at his pictures.
