Dinner for One, also known as The 90th Birthday, is a two-hander comedy sketch, written by British author Lauri Wylie for the theatre. After featuring on the stage, the German TV broadcaster, Norddeutscher Rundfunk (NDR), recorded the sketch in 1962 as an 18-minute black-and-white videotape recording, performed in English by British comedians Freddie Frinton and May Warden. The sketch begins with an introduction in German, followed by the main act in English, and is available online.

A two-hander is a term for a play, film, or television programme with only two main characters. The two characters in question often display differences in social standing or experiences, differences that are explored and possibly overcome as the story unfolds. Instances of two-handers may include theatre, film, television episodes, television series, and radio.
