Like we need another Flame On cameo. There's been, like, 3457893256 of them!
(If you don't know what Flame On is, it's a series of TF2 videos involving someone playing as Pyro going around different servers helping his team win. It's quite rare to find. I don't have the link of any episodes of it with me right now, so you'll unfortunately have to find it yourself. It's extremely popular for the cameos it has.)
