Mr . Callahan Mr . Callahan was the focus of several " Muppets Tonight " skits entitled " At the Bar " , which were only shown in the UK version of the show . The skits were seen from Mr . Callahan ' s point of view . Mr . Callahan was a regular customer at a bar owned by Polly Lobster and Clueless Morgan . Although referred to as Mr . Callahan , he is seen wearing nail varnish and jewelry , and Polly and Clueless make references to him wearing silver lip gloss , and other cosmetics , perhaps suggesting he is a cross - dresser . In each segment , Mr . Callahan enters the diner and sees Polly Lobster singing Rod Stewart ' s " Da Ya Think I ' m Sexy ? " . Polly never gets further than the third line , however , as he then notices Mr . Callahan . He offers him his usual drink , which Mr . Callahan always declines . Polly gives him a new recipe , which usually has unpleasant consequences . Polly gives some kind of reassurance such as " Don ' t worry , Mr . Callahan , those eyebrows will grow back . " After drinking , Mr . Callahan asks after Clueless , whom Polly then calls . Clueless compliments Mr . Callahan on his appearance , then , prompted by Polly , makes jokes about his family . Polly eventually tires of Clueless ' jokes and prompts him to sing . The song is almost immediately interrupted , usually by Polly and Clueless getting knocked out . The segments are a reference to the " Joe the Bartender " sketches from " The Jackie Gleason Show " , in which Gleason ( as Joe ) and a character named Crazy Guggenheim ( played by Frank Fontaine ) would chat with the unseen Mr . Dunahy and then sing a song . Guggenheim , a drunk , would sing in a beautiful melodic voice that contrasted with his personality . Clueless says his sister is eating him and his wife out of house and home . . . literally . She watches the kids ( a " nanny goat " ) . They launch into " Camptown Races , " but Mr . Callahan pelts them with fruits and vegetables . Clueless is attempting to swat a horsefly with a cricket bat . He knocks out Mr . Callahan , infuriating Polly . Clueless attempts to atone by singing a fly - themed variation on " Skip To My Lou My Darling " with Polly , but he is distracted by the fly again and ends up knocking out both Polly and himself . Clueless is not about to become a father , but eagerly awaiting the completion of a junkyard next to his house , because he eats rubbish . He and Polly start to sing " Give Me A Home Where The Buffalo Roam " , but a buffalo stampedes into the bar , knocking Clueless out , which Polly finds hilarious . Clueless has been recycling cans - by eating them ! He and Polly start to sing " Ta - Ra - Ra Boom - De - Ay " but are both knocked out by hammers which come down from the ceiling . Clueless has been manufacturing peanut butter shoelaces as a sideline . He and Polly start singing " Oh Mein Papa " , but are knocked senseless when two five - hundred - pound weights fall from the ceiling . Clueless is going to knight school to learn jousting . Polly threatens to hit Clueless over the head with a frying pan if he doesn ' t sing . Clueless begins a heartfelt rendition of " Beautiful Dreamer " , but Polly has lied , and hits him anyway . Mr . Callahan then hits Polly with another frying pan to punish him for lying . Clueless is going to driving school . Presumably , because this is the last " At The Bar " skit , Polly and Clueless actually manage to finish their song - eventually . They start singing " That ' s Amore " , and a larger - than - life pizza hits Clueless in the face . They laugh it off and finish the song to wild applause . Segments . _ _ NOWYSIWYG _ _
