Meet the Pyro
How about this for an idea for the "Meet the Pyro" video;
The pyro's secret passion is cooking, and instead of talking about his job or himself in his interview video, he decides to use his fifteen seconds of fame to do his own cooking show. I'm sure many of you remember how funny the sweedish chef was, giving out cooking instructions in uninteligeble english? It might seem like a bit of a rip-off, but I reckon that same formula would work great for the pyro! (Can't you just picture him wearing a chef's hat on top of his gas mask?)
Also, instead of putting his delicious creations in an oven or microwave to cook, like any sane chef, pyro insists on cooking everything he makes with a prolonged blast from his backburner. Of course, this reduces his creation (and the plate) to a shell of pure charcoal, but then the pyro presents it to the camera like he thinks it's absolutly mouth watering.
Maybe the clip could end with a shot of him offerring it to his team-mates to eat, and they're all looking at each other and have facial expressions that seem to say, "Oh S**t! How do we get out of this without hurting his feelings?"
EDIT: Actually, that should be the second last shot (the one just before the freeze-frame of all the TF2 classes). The final scene should be a pan-around of all pyro's teammates, eating his latest burnt-to-a-crisp creation in awkward silence with looks of sheer disgust on their faces. Then the heavy complains, "I just vanted a sandvich!"
