All science fiction adjacent shows are legally required to do at least one Inner Space during their run, that episode was just business.

Or when they went to Pluto or something and Ralphie took off his helmet for some reason and fucking died? 😆

There were 2 more body episodes, one where Arnold turned orange and another one where they helped Ms. Frizzle win a field day.

I watched that recently about the digestive path and all, was wondering how they where gonna get through without having them end up in the toilet.

I remember when the Frizz suggested the way out and none of the kids wanted to go through the butthole.

Remember the baseball game straight out a physics book that says "ignore friction?"
