I'm a big time music person (I teach and I'm almost finished with a performance degree), so I do quite a bit of reading on random musical instruments, composers, etc. I came across this amazing online dictionary on just about every musical term in existence, and the guy's pronunciation of glockenspiel seriously just cracked me up. Listen to that, and then listen to semihemidemisemiquaver (I didn't do the math, but I think perhaps it's a 64th note?). Also pianisissississississimo.
edit: Way off.. well off by a degree, anyway. It's a 128th note. And here you go:
