No littering?? OK, Brian Reis, maybe YOU are a robot who disposes of trash via a crazy robot arm that comes out of your head…in which case it looks like you're not allowed on the subway, sorry.

“No plugging into the Matrix”, obviously.

no one with noses that grow like strange angular tree branches with geometric fruits hanging from the ends of them. ive seen water fountains that people with noses that grow like strange angular tree branches with geometric fruits hanging from the ends of them can't drink from either. CHANGE my ass.

No touching the electronics? Sorry if I'm ruining this thread with a real guess.

No independent thought.

No flowcharting on subway walls.

No cubist projectile vomiting

No gravity defying kinetic sculpture

Do not make circuit boards while the train is in motion.

NO KIDDING! two drunks walk into a bar, the third one ducked.

No dangling mobiles out of your face sideways.

Do not point at things below your sightline.

No giving directions to tourists.

No making flowcharts, obviously.

no speaking in diagrams?
