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.
