Maybe this is a little weird but Barry might get more traction with Geoffrey if he were diapered himself for bedwetting; besides he'd probably get more attention from his wife.
Being a parent of 5 children, aged 20-30, 2 females & 3 males; I find the idea that a mother would ground a 21 year old to be just a bit much. I would expect that the daughter (Chelsea) would be packing her bags and moving in with a friend.
