PJ Kirby and Kevin Twomey are two Mammy's boys from Cork who are always up for a skit. In The I'm Grand Mamual, they take well-worn expressions that their mams have always said, and share hilarious and heart-warming stories from their lives where these sayings have rung true – from schooldays to holidays, coming out to going out, and sustainable thrifting to end-of-night shifting. The I'm Grand Mamual is a big-sisterly companion for taking life in your stride. Mam might always know best – but Kevin and PJ will show you the rest!
