I remember the tail end of an ep and never saw the whole thing. In it Maude picks up the phone and (Walter?) asks "Who're you calling?" and Maude says, "John Wilkes Booth" and Walter and Tom grab the backs of their heads. I'm wondering, what was the episode about and if anyone has a synopsis of the whole thing (I don't get what the reference to Lincoln's biggest headache was in relation to the show because I didn't see the entire ep http://www.sitcomsonline.com/ubb/wink.gif )

It was late one night by the pale moonlight all the vegetables gave a spree (http://moonjaguar.com).

The episode is the one where Maude's mother comes to visit. At the same time, Walter is starring in his own TV commercial, plugging the President's Day sale at his appliance store. In the undignified commercial he dresses as Lincoln, and when Maude sees it, she makes the John Wilkes Booth joke you remember.
