When I was younger I used to find it pretty surprising how my Dad could call my Grandad (his Father-in-law) names and get away with it.
I remember later telling Mum in the most concerned voice; "Mum! Dad called Grandad DICK!"
Later I found out this was due to his last name being Whittington and had something to do with the story of Dick Whittington and his cat.
