This might be a really really stupid question, but I have no idea what the answer is to this question, a friend of mine asked me and I laughed cuz I had no fucking clue.
Why are there two speeds on turntables? 33, and 45? Is there a reason? Does a certain speed have better quality? Can you manipulate one speed better then the other. I realize you can fit more time on a 33 cuz it's moving that much slower, but there has to be other reasons then that.

Higher speed means better high frequency response due to effectively shorter possible recorded wavelengths.
Warping error (as the record moves up and down vertically) increases though but wow and flutter will have less noticeable effect.
There could be more to it - Skywarp's the vinyl tech expert, give him a shout.

Well I'm not 100% sure on this but besides what Joel said, the 45 rpm records are easier to press and also a little more resistant to physical damage. Slight imperfections due to pressing or rough handling should be less noticable on a 45 because there is less audio per unit of length and so a scratch shouldn't damage or distort as much of the signal as on 33 ...
i think they only usually press 33's so they can fit more on... ah i aint no expert in thiseither so thats my educated guess

Also, with 33s the grooves are usually packed closer together than with 45's. A lot of times 45's can sound a bit cleaner than the same song on 33 but then again, that all depends on the quality of the vinyl used and also the pressing itself.
it has to do with science (more or less)
the 45 rpm records are smaller, so they need to spin faster so that the music doesn't sound slow, as with the 12" records, they need to spin at a slower speed, because they are bigger, hence the 33 rpm
basically, the bigger the record, the slower the table speed needs to be
Shockwav: what are you talking about ? 12" can be pressed at both 33 and 45 so the size of the record doesn't really have anything to do with it. By your logic the deck would have to change the speed as the needle moves towards the center of the record in order for the music to run at constant speed...
