Sharp made an auto-reversing turntable, it played both sides, front-loaded like a CD player. I have never seen one, despite being an old guy who is of that era. There were but a handful of turntables that could do this, so that’s a lot of production effort for a joke but a few were equipped to get.

There were a lot of eight tracks during that time, though, so sibling comment is more likely correct.
