We will discuss a way of explicitly constructing ribbon knots using one-two handle canceling pairs.  We will also mention how this is related to some recent work of Yasui, namely that there are infinitely many knots in (S^3, std) with negative maximal Thurston-Bennequin invariant for which Legendrian surgery yields a reducible manifold.
