London underground at rush hour is, in short, a fucking nightmare.

Never before have you seen so many people squished into such a confined space in such a short space of time.

It even gets to the point where it simply isn’t possible to get any more bodies onto the train because there isn’t a molecule of space remaining.

That is… until someone throws up, like they did this evening.

Then suddenly a whole shitload of space miraculously becomes available.

I call it the Moses Effect.
