Alan Thicke then
A two-time guest star on Married With Children, Alan Thicke played a businessman called Henry who dated Shannon in season 10, and a car dealership owner who dates Peggy in season 11.
Perhaps the writers hoped that audiences wouldn’t notice he’s played two different people! Coming from a successful seven season run as Jason Seaver on the sitcom Growing Pains, Thicke was already a family name.
