Harry Anderson returns as impish scam artist Harry the Hat. Sam (Ted Danson) enlists Harry's aid to avoid an embarrassing situation stemming from a wager made between Cheers and Gary's Old Towne Tap on the occasion of St. Patrick's Day. Since this may be the last time that Sam has an opportunity to win out over Gary's, Harry will have to pull more than a rabbit out of his celebrated hat. ~ Hal Erickson, Rovi
