Guys with guitars and good voices annoy me. Not because I dislike music, but because I like getting with girls. In my eyes, dudes who can play the guitar and sing well at parties are using performance enhancers (not unlike the foreign accent). You shouldn't be able to use anything to hook up with a girl that you can't carry on a plane. Here I am slaving away, putting in hours each and every day to make sure my wit, wardrobe, and facial hair are making me as hook-up-withable as possible (did you see how delicately I put that?) Meanwhile, it seems like all the John Mayers of the college scene have to do is throw on a shallow V and a pair of vans and play "a song they wrote about their little sister" to bag the girl I've been throwing game at all night and texting for a week. All of a sudden it doesn't matter that this hipster is wearing 2 rings and 3 bracelets because he plays an instrument and sings like an angel. I guess the moral of the story is that if a skill is not on my tool belt, it should be socially outlawed.
P.S. If by some act of truly divine intervention I do learn one song on the guitar, you're all in big, big trouble.
