The didgeridoo would be fun to learn how to play.

Good pick. It looks so hard to play, but I have heard it done well.

As for me, I don't play any instruments. Here's my list from what I want to learn first:

-Piano (I know a little, but not enough.)
-Bass guitar
-Violin
-Drums
-Cello
-Voice

I've played guitar for 7 years now, however I'm eying a banjo right now, think I'll save up some money this summer and pick it up sometime in August if it isn't gone by then.

you should get a ukulele... and annoy the living fuck out of your friends.

I'd love to learn the acoustic bass. I heard my music teacher playing it and it sounded amazing...

Haha believe me I can do that without the use of a musical instrument, that includes voice.

Me too, living with me my roommates have to put up with A LOT of: piano noises, bad guitar, and singing (in the shower, in the kitchen, everywhere).
