outside we 're met by a scene that seems straight out of those bad acid trips you see in the movies : the stanford marching band in what appears to be mostly their underwear and glow-in-the-dark necklaces and bracelets and stuff , rocking their respective instruments , trumpets blaring , drums beating , cymbals crashing , the school mascot in his big green pine tree costume zooming around like a crazy man , a bunch of half-dressed , partially glowing students jumping and bumping and whooping and laughing .
