Though it can be fun to catch inconsistencies in TV shows, callbacks to previous episodes or established backstories are, in my opinion, so much better.
But what's the best TV callback of all time?
Maybe you love that, on The Office, Pam uses Jim's teapot gift later in the Finer Things Club.

Or maybe you love that Walter White from Breaking Bad crosses paths with his pants from the pilot in Season 5.

Or maybe you love the Friends consistency of Angela Delvecchio.
