Full House (1987)

Season 5: Episode 7

After school is dismissed for the day, D.J. goes to the Golden Gate Nursing Home to visit 75 year old Eddie Johnson, her "adopted grandparent" in the Adopt-A-Grandparent program. At home, Stephanie and Kimmy have a disagreement -- Kimmy seems to think her dog Coco is smarter than Comet, so they agree to invite all the dogs that live in their neighborhood into the Tanner family backyard for a little dog show in order to settle this. D.J. has promised to be the judge, so at the end of her visit with Eddie, D.J. tells Eddie about the dog show. Eddie wants to see the show, so he sneaks out of the nursing home and goes with D.J. to the house. At home, D.J. notices Eddie acting strange, like he doesn't know who D.J. is.
