The sexiest instrument in the entire world, next to the tuba. These instruments are so studly that anyone that plays one is instanty recognized as a god, stud, or downright playa.

A sousaphone is commonly referred to as a tuba. This is the tuba of choice for many marching bands. The sousaphone section can consist of 1 person, but many bands have up to 20 of these very awkward instruments.

Warning: Use of a sousaphone without proper training can result in the injury of the player or those around him.

Warning: Sousaphones are not to be used during lightning storms.
Sousaphones are difficult to transport on buses and in cars.

40 pounds of ultimate hotness. Those who are not seksi enough have to settle for playing a less hot instrument like the euphonium or trumpet. Those who are least gifted have to be demoted to the woodwind section, or even the drum line!

It will often cause you back problems, but who cares when you get all of the chicks! (Or guys for those less effeminate female sousa players.)
n00b: "Why is that guy's sousaphone white?"
Me: "Its because nobody likes him. Oh, and because even though he is 30 or so, he cant lift a brass sousa, so he has to carry white trash. He probably was a trumpet player"

Stupid people who dont think: "Isnt that heavy?"
Me: "uh, no, see how seksi I am?"
them: "oh, I forgot!"

Stupid people again: "Why dont they make pads for sousaphones?"
Me: "They do."

other brass: "Why did you pick the sousaphone? its so heavy!"
Me: "You dont choose to play sousaphone, it chooses you. Either that or the director forces you to since nobody wants to until they have."
