For an interesting character, you could try a mage / thief combination. It can get a bit complicated, but the amount of stuff you can do is really cool - all the stealth stuff and traps, a load of fun spells, and after a few levels you're not too bad in a fight either, especially if your dexterity is high and you focus on dual wield skills.
If that's a bit too much for your first character, just go with bard, which is a sort of jack of all trades character anyway.
Edit - nah, he's serious about the monk. I never play them though, because you don't get to use all the cool armour and weapons you find, because monks work best unarmed and unarmoured.
