Goof: At the end of one scene, the babies are in their regular clothes instead of their pajamas.
Goof: During the bingo match, listen closely to the numbers; they aren't the same as the actual bingo formation, which is 1 to 15 under the B, 16 to 30 under O, etc. The announcer drew the numbers as "N-2", "O-2", etc. At first, I though this was one of the center's techniques to keep the patrons "quiet and relaxed" by not winning and yelling out "Bingo!", but I later found out that Grandpa later won with the erroneous numbers.
Goof: When Stu and Didi are in the garden, Didi is wearing a purple sweater but when she is zoomed in on and says" They're so Sweet" her outfit is the same red dress she always wears.
Goof: When Grandpa has 1 more square to go, the bingo board already has a bingo diagonally.
Goof: In "Lady Luck", when the bingo caller says O7, Grandpa puts it on an I square.
Grandpa: If a promise you don't keep,
May it haunt you in your sleep.
And as you lie beneath your quilt,
You will have a conscience full of guilt.
Grandpa: (Deciding to break his promise of not going to a pinochle tournament by saying this rebuttal) But if it's cards you like to play, Play all night and sleep all day!
"Lady Luck" was David Doyle's last episode because he died of a Heart Attack.
