The Neighbors' Thanksgiving is going to get very meta.

On Friday's episode (8:30/7:30c, ABC), Larry (Simon Templeman) and Jackie (Toks Olagundoye) barge into the Weavers' house — where they're prepping a turducken, natch — to announce that they had just watched a Nick at Nite marathon of classic Thanksgiving sitcom episodes and they now know the true meaning of the holiday. 

Fall TV Report Card: How's the new class doing?

"The Nick at Nite marathon taught us that Thanksgiving is a special day filled with troublemaking in-laws, cooking mishaps and unpleasant surprises, which makes it a holiday nobody really wanted, but in the end everyone really needed," Jackie says in the exclusive sneak peek below.

"I'm going to go out on a limb here and say there will be no unpleasant surprises this Thanksgiving," Marty (Lenny Venito) replies.
