A few days ago, I went to the mountains and bought a particularly stinky piece of cheese. I packed it properly with a plastic wrap, then a Tupperware container, then another Tupperware container, with an extra bag over the whole thing.
And yet, somehow, the entire car smelled like cheese for the whole trip.

This got me thinking. My companion and I were both travelling with probably a bunch of shit inside us, and not a single molecule of it seemed to escape.
So how is the anus so airtight? What kind of black magic is this?

Anyway, lesson learned. Next time, I’m just putting the cheese up there.
