Well, a nonorientable one, and IF you consider it as a 2D manifold (if I'm remembering things right from long ago) it's unbounded above and below in the same manner a horizontal line is to left and right. We usually just look at a section of that and call it a "Mobius strip", and give it top and bottom edges. But I don't think that's what Don was thinking of.
