At the Drunken Clam, Peter, Quagmire, Cleveland, and Joe discover that Medieval Castle, a satired version of the Medieval Times restaurant, is being put up for auction. They decided to go for it.
The guys lose the Medieval Castle auction to Mayor West and his cohorts. A fight ensues and the gang fails spectacularly as they've accidentally burned the place down instead. In typical Family Guy randomness, Quagmire discovered that Mort has received a date courtesy of Tinder. Intrigued, Quagmire decides to use the app to score with women. As he climbs the leaderboard of success, it becomes an addiction.
The episode is titled "The Dating Game" which is on the 15th season of Family Guy.
