You are far too hesitant to post questions. There has been a distinct lack of interesting questions on MO lately and I think this would be a welcome addition.

It's coming directly off of this question: http://mathoverflow.net/questions/335/is-every-functor-a-composition-of-adjoint-functors/336#336It seems like a good question on its own. But I feel like ...
It seems like a good question on its own. But I feel like it's coming directly off of the question above, which got 17 votes. So it's basically like "this question had an answer with a counterexample, so is there another counterexample if we add more restrictions?"]]>
