I hate being asked hobbies as well; I especially get weird looks when I'm nicely dressed (and by dressed I mean literally in a dress) and at a party or something and reply with "well I like playing video games". People seem to find it hard to believe that a socially-capable person can enjoy playing something more complex than Bejeweled.

I study philosophy, but since it's rather hard to explain exactly what it is (and even harder for the majority of the population to even grasp the basics the first time they learn about it), I try to avoid answering. It gets tedious. And even when people (usually girls, for some reason) know about it, they answer "So you think alot, huh?".
I tend to stare off somewhere and answer a dry "Uhu.."
I'll hopefully be studying palaeobiology this year; when I tell most people this they end up halfway through a spiel about Rome before I inform them that palaeontology is more about really ancient animals than less ancient civilisations. Eventually I just go the "like Sam Neill in Jurassic Park" route to explain what I mean.

Edit: Even worse is when guys ask, for when I answer, they tend to reply "So what will you do when you're done?", to which I reply "Be happy, I hope".
"Well, yeah, but what will you WORK with.." and I tend to lose and it inform them that having a high-paying job isn't what life revolves around.
I went to the Australian Musuem the other day and somehow managed to get into a conversation with some desk lady - a DESK LADY - who then asked me "So you like being poor?" when I told her what I want to be.
My reply was somewhat similar to yours except I nearly threw a taxidermied echidna at her for emphasis.
