How many people have been at a party when a random guy pulls a guitar out of his ass and starts singing? I swear to god, it's never the same guy but I would like to think it's some sort of worm hole in space that just shows up if 20 or more people are in a living room together drinking. What do you do when this happens. I usualy walk over and put my hand on the neck and shake my head at the guy. But this never works. Sure enough 30 minutes later there he is squaking out some Nickelback awaiting a good thrashing!
