I’m sure someone has talked about this before but in the episode “Planned Obselescence” when Mr. Peanutbutter is in the car and Diane is on the radio. They bring on a Russian cosmonaut named Laika. She’s the one who discusses Planned Obselescence. She is introduced as the first woman in space. Laika is the dog that the Russians actually sent up into space in the 60’s. I love this show’s little details.
