Help! My Dad is a LAG!

[T. Poker]

Hi guys I don't really know how to tell my Dad, but I've seen his play in home games and online and he is definatley a LAG. He raises any 2 cards and he doesnt care what position hes in. He just keeps on blasting at the pot. How should I go about telling him he needs to tighten up his play?

I was thinking maybe one day when he comes home from work, I would get his home game buddies, myself and our family to confront him about it. I could print out some hand histories of his play and read them outloud in front of everyone at the intervention. I dont want to hurt his feelings, how is the best way to approach this?
