What would the best/worst rockband instruments be?

(To the mods: sorry this isnt under the proper Rock Band forum, the mobile site is still janky)

My workstation has been broken for some time now, and I started thinking, as one does, about Rock Band. Mainly on how there is a plethora of unexplored ideas for over-priced plastic instruments!

I recommend the noble "Pro-Triangle" and "Pro-12-Sting-Guitar"

What are your suggestions??

Kazoo.

Here's my plastic whiskey jug! Blow air over the top to match the beat of the song.

Saxophone would rock, imagine the funk you could lay down with all those buttons

heroin needle

@toxeia: rock band hillbilly!

@devilzrule27: can it come with a plastic hooker too?

Bagpipes!

Vuvuzela

A plastic tv to throw out of a hotel window.

Fiddle.

Accordion! Or a giant Harp

Oboe, harp, penis.

Give me some horns so I can play some ska.

Claps.

I was going to say violin, but that could actually work with a motion sensor bar thingy... it probably wouldn't be cheap, but it could be a thing that doesn't suck. Same with a theremin, if they could manage to make one not insanely difficult to play.
