Mrs Brown's Boys - Season 1 Episode 5

Suffering from pre-nuptial nerves, Dermot shuts himself into the cupboard under the stairs, so he's still there when Father Quinn arrives to give the happy couple their premarital talk. What finally draws Dermot out is Buster's moving best-man speech (initially he could find nothing good to say about the groom) and he promptly asks Agnes if he and Maria can live with her. Agnes also discovers that her son Rory is gay after Cathy gives her a book on homosexuality, but she accepts the news with her usual tactless tolerance: "I know all about your illness."
