At my school:
Flutes are brutal and cut-throat
Clarinets are cool but strange
Low reeds are disfunctional but still the best
saxes are lazy and, well, lazy
trumpets are loud and egotistical
horns are awesome but...interesting
euphs are insane and hard-core
trombones are...trombones
tubas are tall and funny, well at least one is
