I remember seeing part of a movie in third grade.
I thought that it was a live action Magic School Bus movie, but it’s not.
What I remember is two boys and a girl going into school at night and sneaking into the boys’ bathroom. The girl asks “What are those? We don’t have them in the girls’ rooms.” They tell her it’s a foot bath, and so she takes off her shoe and washes her foot in it, giggling as they flush it.
One of the guys had glasses, and he kind of looked like a live action Arnold from MSB.
That’s actually from an episode of “The Adventures of Pete and Pete” called “”All-nighter.”

Oh, it’s from Pete and Pete? It’s been a long time since I’ve seen that show thanks!
Solved!
OK, I’ll mark this solved and credit rising star Cotopaxi with another Solve.
Thank you, I remembered it as a Harry Potter movie, and thought Harry and Ron tricked Hermione into washing her feet in the urinal.
