I asked it what season of Community is referred to as “the year of the gas leak”. It answered season 2. I said “that’s incorrect”. It apologized and said that it’s really season 3. “Still wrong”. “I apologize, the year of the gas leak is season 4. Multiple episodes in season four refer to the gas leak”. I pointed out that it was part right, and it confidently corrected itself, now the year of the gas leak is season 5.

Fans of the show know that the correct answer is season 4, but it’s a joke starting in season 5 about Dan Harmon not being the show runner for a year and whatever happened in season 4 can be ignored. I’m pretty sure I found the Reddit thread that would have created the confusion.
