Andy Capp is an unemployed, lazy slouch who likes nothing better than drinking beer at the local pub. He is constantly nagged at by his wife Flo. In 1960, he spawned a spin off, as a new children's comic launched called Buster. It's cover star was Buster, Son of Andy Capp. Andy never appeared in Buster's strips, but Buster's mother looked exactly like Flo, although her name was rarely used. Oddly, Buster has never been mentioned in Andy's strips.
Another Daily Mirror strip, Mandy, although not actually a spin-off from Andy Capp, was originally titled Mandy Capp.
