Author, playwright, stand up comedian and milkman, Brendan O'Carroll was sitting with his agent and manager Rory Cowan. They were at the RTE studios - the biggest television and radio network in Ireland - when it was mentioned that the company were looking for short plays.
"I've written some five minute comedy plays." Brendan piped up. He hadn't, but he recognized an opportunity when he saw one. All attention on him, he made stuff up, speaking as quickly as he was thinking it. "They're about a Mammy in Dublin with a big family." He was thinking of his own mother, who'd raised eleven kids. "She speaks her mind, but gets it wrong a lot."
Rory looked at him. He knew nothing about this. But he wouldn't. Brendan was making it up as he went along.
"One of the sons is based on Rory." They all knew what he meant. Flamboyantly camp. "But Mammy hasn't even worked out that he's gay. Funny stuff."
Brendan got the gig. He had to rush home and quickly write ten five-minute radio plays. They were so successful that they turned into stage performances, with the venues getting bigger and bigger, then spilling out of Ireland to tour the world.
At one stage show in Britain, a scout for the BBC was watching from the audience. Stephen McCrum approached Brendan afterwards to see if he'd be up for turning the play into a television sitcom. Brendan thought it was some kind of practical joke.
But it wasn't and now the award-winning Mrs Brown's Boys is into its third season. It's slowly taking over the world.
Yet twenty years through various incarnations, Brendan hasn't built his Agnes Brown brand alone. He took his whole family with him! Here's a look at who shares the screen with him; and how they're related in real life.
