One of numerous short sketches from various sitcoms and sketch shows of the time, each interspersed with the repartee of host Frank Muir in this one-off special, The Funny Side of Christmas.

Granville is looking forward to it, but Arkwright's anticipation is tempered by the knowledge that Gladys's mother will be there. (thetvdb.com)
