Whats wrong with having some committment to your material, learning the words (with some thought as to what they mean - like an actor does), thinking about how to present it(perhaps a few words to make it accessible to people unfamiliar with your particular strain of genius) - working out an accompaniment that's in the right key for your voice and doesn't sound a tedious argument of insidious intent, and turning up with your guitar in tune.

Weelittledrummer, you're assuming they don't do that? Anyway, this is supposed to be a FUN event. In our parts, it only takes place once a year, at a festival. The participants AND the audience enjoy it immensely. It challenges people'e creativity, and it's surprising to see what can come out of these combinations - often something quite exciting and new. Sorry your life has to be so serious.
