M*A*S*H and the Health Care Bill

I remember a M*A*S*H episode where a long chain of "favors" developed through the first half of the show, only to unravel in the end when someone in the chain either reneged or couldn't follow through on his/her promise.  Then all the deals were undone back to the beginning in a house of cards

One can only hope that the same happens with the health care "deals" and this bill.

Now ... what episode was that?  I've been poking through the episode descriptions on Wiki.  There's one called "Wheelers & Dealers" in season 10, but the brief description doesn't match the memory.  Might be another one.
