That Newhart one was a classic. That and Lou Costello's eating oyster stew are my all time favorite comedies. I suspect Rawly (as he wrote it) also brought back potatoes. There were many phamplets written telling about all the dire consequences of actually eating such vile things. One expressed the belief that it was poison and it was a plot by the English government to kill off all the Irish so England could sent their excess population to an empty Ireland. Reading them now is as funny as Newhart's 'But Walt, come fall, and we're up to our a-s in leaves over here.'
