Hah! Can we clarify that I'm absolutely not at all an expert on hotboxing?! But as for the TARDIS- while it's not infinite it's certainly vast. But perhaps theoretically achievable if the main control room is shut off from the rest of the ship.

You can increase the efficiency of hotboxing your TARDIS by jettisoning rooms; just make sure you don't jettison the room you are hotboxing in. Admittedly, this advice might only apply to Type 40 models...

I'm sure the Tardis could induce a similar effect in the average pudding brain without tripping the smoke alarms. (Imagine the random fire drill and its your turn to check every single room.)I'm sure the Tardis could induce a similar effect in the average pudding brain without tripping the smoke alarms.
