According to the official Twin Galaxies' world rankings, George's (Jason Alexander) Frogger high score of 860,630 would have at the time been the #1 score in the world. As of 2015, it would rank #3.
Jason Alexander (George) did his own stunts when he jumps on the pavement. A large shard of the Frogger game almost hit him in the head.
Game Buyer Magazine, the successor to Ultra Game Players Magazine, cited this episode as one of the reasons they re-reviewed Frogger (1997) and gave it a higher score than previously.
The sound effects heard during George's (Jason Alexander) moving of the machine are actual sounds from Frogger. They were added to play in time with his movements. The sound that's heard shortly after the machine is smashed by a truck is the "squash" sound when the frog is hit by a vehicle in the game.
