4 minutes, 32 seconds into episode, flashback diner scene, it's "Criss-Cross."

This flashback scene is the same footage used to feature some Happy Days characters in the sitcom "Love, American Style."

5 minutes, 41 seconds into episode, look closely at what appears to be a route or shipping sticker on the head of the game.

Definitely "Nip-It."

Another shot of the new game.

To the left of the pin, notice the Seeburg jukebox, featuring a clear glass, unlike in the intro, where it's fogged over, maybe for copyright reasons.
