Something caught my attention when I finally got around to watching the tape of "The Frogger" episode...
When George is standing behind the kid at the pizza parlor, there are a couple of seconds of the kid playing "Frogger", and the High Score of the machine is visible at the top of the screen... but it's only 7,200 points, which also happens to be the same as the score to the left of the kid's current game.
I rewound a couple of seconds to make sure I saw it right, and I did... Then, right after, the screen changes to the high score screen, and there's George's long-lasting high score.
