Lyric discussion by Whiffet 

Cover art for Prom Theme lyrics by Fountains of Wayne

This is a great song of cynicism. He builds up how great this night is going to be throughout most of the song and then actually talks about the night itself: they ran out of gas, everyone is getting sick and passing out on the beach...Also refer to the beginning where he says "We'll vanish in the haze...We'll grow old and lose our hair...It's all downhill from there..."
