Nailed it. You must be a college student, because that joke was founded on information that nobody really retains.

Or maybe you're like a historian, who DOES retain it, and have to watch everybody around them dick everything up the same way they did a hundred years ago.

Either way, good short.

cute, short, no glitches. Nice work.
It didn't feel 'paradox-y' in the most modern sense, but was still within that realm.

I don't get how in the world this is a paradox, it's more of a sketch where a character does something but is disgruntled by something he can't control. What I mean is that there are no premises that contradict themselves and a final product that negates both premises and at the same time affirms both. We got A; man throws bottle in trashcan, B; trashcan spits anything that's thrown into it, and finally C; Trashcan becomes eldritch black hole of destruction. It sounds like a cause and effect relationship rather than a paradox...

Now i'm hoping that this doesn't happen to any janitors now

this is really good, this deserves to be on the front page!
