The song is a parody of the Tammy Wynette song "D-I-V-O-R-C-E", and Connolly's version to date has been his only #1 UK single, though in the late 1970s he had a further two UK hits which parodied contemporary songs. He later dropped musical performances from his act.
"D.I.V.O.R.C.E." has a similar theme to Wynette's original in that the events in the song lead to a couple divorcing, however in Connolly's song the words are spelled out for the benefit of a dog rather than for a child as in Wynette's version, and the divorce is sparked by a riotous visit to a veterinarian that results in the husband being bitten by both the dog and his wife.
Some versions of the song, such as the live performance included on the album Get Right Intae Him!, are censored, with the words "f-ing C" being bleeped.
