TF2 - Thrn Ur furnd hus crps a frt rmm srm wrrter!

I subscribe to the idea that the Pyro and Engineer are friends, but I've wondered aside from sticking with each other during battles, what could they have in common? Then, a friend talked about getting kills while dead because the Sentry was intact, defending the point. And I thought, oh! The Pyro often gets kills while dead as well. The two of them can talk about that over tea!
