Welcome to TheSimpsons, a community for discussing everything related to America's non-prehistoric cartoon family, The Simpsons!

Right about now, you're probably saying, "Troy, basically every post starts with 'Guess the Episode', is that all this community is?"

To which I say you've got some attitude, mister.

But no, any Simpsons content is allowed in this community, although we do ask that you keep the shitposting over in !simpsonsshitposting@sh.itjust.works.

Guess the Episode "Rules"

These "Rules" aren't real, so if you think of something clever, do that instead.

Its not a sundial (which measure earth's rotation), it's a meridian line. I think they can be set up anywhere, but they're measuring exact noon, and the ~~light would "travel" north to south.~~ It travels west to east, the line on the ground is oriented north/south. Lenny is facing north.

It will travel north to south (and vice versa) throughout the year, but during the day ~~east to west~~ west to east surely.

Shadow would move east to west, beam of light moves west to east.

Yeah the line on the floor is what's North/South. The beam of light is moving west to east.

The beam of light moves the same way as a shadow would. Think of it as a "gap" in a shadow.

No it reverses it, the hole in the ceiling is creating a pinhole camera effect.

https://en.wikipedia.org/wiki/Palermo_Cathedral "The device itself is quite simple: a tiny hole in one of the minor domes acts as pinhole camera, projecting an image of the sun onto the floor )" - It never specifically says west to east but that's what's it's saying.

The pinhole effect reverses the image itself, but that is irrelevant. The beam of light will always travel west to east on the northern hemisphere.

The 'image itself' is the entire sky, which is being flipped.
