That janitor just goes from building to building helping people.

10-panel SMBC comic update.

All the panels are dialogue-less.

Two researchers are writing equations on a chalkboard.

A janitor watches them from afar.

The researchers leave as the janitor is still mopping the floor.

The janitor walks up to the chalkboard and writes on it with purpose, admires what he wrote, and leave late in the evening.

The two researchers return at dawn, and are shocked by what is written on the blackboard.

Over their half-erased equations, the text “ChatGPT, do a breakthru, no mistakes, thankx.”
