The clarinet seems rather popular for a school instrument - I played for a few years but lost interest in high school.
I've always wanted to learn the guitar. My dad plays a lot and collects them too - last time I checked he had over 15 guitars and 7 or 8 amps. He gave me his Ibanez guitar and a Peavey amp last year, but I still haven't taken much time to sit down and learn.
