Joining Helen and Ellie this time are their dads, Tim and Jim. They talk grandfatherhood, politics, dogs and the secret to having a long and happy marriage. Well, a long marriage.
We test Jim's enclycopedic knowledge of London pubs and Tim discusses getting heckled by his congregation. Plus, we quiz the grandads on modern life - tune in to find out whether Jim knows what a Kardashian is and what Tim makes of Grindr.
And finally there's just time for some Scummy Mummy Confessions. Do send yours in via email - email@example.com - or Facebook. We're on Twitter too: @scummymummies
