I totally disagree with Joe. Stuff it in. You very likely have BB beat, so your equity in the sidepot will finance a decent portion of your investment in the main pot. If CO has KK, so be it, but you are most likely ahead here with a set against these short stacks who basically committed preflop. And you have a draw to the nuts and all kinds of possibilities for making the best non-nut hand.

I crack people all the time with bottom set, for much bigger pots than this. I think bottom set is highly underrated.

I would have folded to the raise preflop though, cause you realy don't have the implied odds you need to call that raise with a hand like this. You are not going to flop a worthwhile hand very often, so you need to have the potential to stack someone big time when you hit to make it worthwhile.
