Oh man, newbies and low skilled players in this game are an endless source of amusement. My friend and I try to rationalize their behaviour, or get into their heads, trying to explain their thoughts. 'Oh hey, why is there an identical heavy right next to the one I'm healing? Oh, why is there only one now? Did he drop his Sascha? Huh, must have been server lag... ignore and continue.' (in case you did not understand, we were a spy disguised as the very same heavy that the newbie medic was healing, then Your Eternal Reward'd said heavy's back yet again. The medic was probably too new to realize what happened and continued to heal us after we 'disappeared' the real heavy). Or 'they must have read or seen somewhere that medic and heavy is a winning combination. Well, I hope we don't discourage them from playing the game as we crush their hopes like that'. 'Ahh, he blew himself up again... Will he make it this time?... (brief pause) That demoman here is simply the Chosen One.' And so on and so forth. One person playing and the other one doing the commentary beats playing cooperatively together, in my humble opinion. Turns my friend's tendency to nerdrage into comedy gold, too.
