Radio fucker: omg, did you hear that new song it's great
Me: yes, i did, and i was deeply annoyed and saddened that it can pass for music. i much prefer school of fish
Radio fucker: oh, yeah? well it's on the radio, let's see your precious school of fish top that, i mean no one's ever heard of them
me: well, school of fish had quality songwriting, intoxicating melody's, rich inspirastional lyrics and a great voice
Radio fucker: those things exist?
