One potential idea could be to get your dad some Grey's Anatomy merchandise. This could include a Grey's Anatomy t-shirt with a quote or image from the show, a Grey's Anatomy coffee mug with his favorite character on it, or a Grey's Anatomy inspired cookbook featuring dishes from the show. You could also consider getting him a subscription to a streaming service like Netflix or Hulu so he can watch all the Grey's Anatomy episodes whenever he wants. Additionally, you could buy him tickets to a Grey's Anatomy themed convention or a tour of the set in Los Angeles if he's a big fan.
Or you can get him a star map with the date when he welcomed you in this world.
