Someone on Reddit asks what to do after they do this to their garbage man:

Two nights ago I emptied a Shop Vac into my garbage can. I had been using the vac to suck up sawdust. Dumb idea.

This morning I happened to see the garbage man empty the container. The truck uses a machine to shake the container as it empties into the back. The second it started shaking the bin, a massive cloud of sawdust went up in this poor guy’s face.

There are legitimate, useful responses, but Reddit is far more interesting when someone posts a ridiculous idea and people build on it, and this thread of responses had me gasping for breath.
