Audio problem: When Judy asks "But Grandpa, why didn't you tell us what was going on?" towards the end of the episode, she is speaking with Jane's voice.

Starring: Mel Blanc, Daws Butler, Janet Waldo, George O'Hanlon, Penny Singleton
A Date with Jet Screamer - S1-E2
Other mistake: In the song "Eep Opp Ork Ah Ah" (sung later in the episode), the singer's lyrics say that it means "I love you", but it was first revealed by Elroy and his friend who first wrote that same code to mean "Meet me tonight".
George Jetson: Jane. Stop this crazy thing.
Cogswell: There's only one thing worse than war and that is business, and Spacely has declared business on us.
Mr. Spacely: Jetson. YOU'RE fired.
