Visible crew/equipment: Early in this episode, as one of the couples walks through the kitchen door into the living room, you can see a hand on the door pulling it closed.

Factual error: When Olivia (or whoever) is teaching Russell how to play the Nintendo game she tells him the controls and includes "C and D". The old Nintendo system had no C or D.

Plot hole: When Theo is complaining that his father is inviting too many people to his graduation, he says "I saw him in the backyard 5 minutes ago hosing down the beach chairs", but this couldn't have been possible because in fact, Cliff was upstairs right before that scene, and then went straight to the living room, so there's no possible way that Cliff could have been in the yard at the time Theo had said he was.
