"The Turkey That Came to Dinner" is the thirty-third episode of Teacher's Pet. It is also the series' Thanksgiving episode.
It's Thanksgiving, and Leonard's grandmother Grandma Rose (who is also Mary Lou's mother) is visiting for the holidays. Since she is allergic to the pets, they have to stay in the laundry room. After she arrives, she brings in a live turkey from her friend's garage sale for dinner, as the pets try to find a way to prevent this from happening. In the meantime, Spot becomes disdained with Leonard because he promised to check up on them every few minutes or so. This never happens though because Leonard's grandmother brought over an old retro video gaming system, to which Leonard slowly becomes addicted to.
