One of the kids must've had a time machine

This is set in 1960 and in the opening, a kid is playing Xbox 360. Video games would not become a thing for another 20 years or so. Also, the Xbox 360 wouldn't have been invented for another 45 years. Wow, this has a lot of continuity errors. If they were there on purpose, for humor and whatnot, I could understand but these were not intentional and this isn't like Austin Powers or Futurama where technology gags pop up every now and then.
