Dr. Killinger's line that Dr. Venture will find 'only what he takes with him' in the magic murder mystery bag mirrors what Yoda tells Luke Skywalker before he enters the dark side cave in Star Wars: Episode V - The Empire Strikes Back (1980).
First showing of the control center. The Venture compound is based loosely on the Futurama building from the 1964 world's fair and the round disc shape of the control center accurately reflect that design.
According to the DVD commentary this episode had an alternate ending where Sergeant Hatred was in his hover tank getting his letter from the guild shouting "Honey! Pack up your tipi we're moving!".
