My father just got a call to a yard where a discarded deep was sitting one-corner-down in an empty shallow out in the tall grass and weather. No lid. No bottom. 8 old combs in it though. Wouldn't make it through a Vermont winter, but does show the attractive power of combs to swarming bees.
...and yes, I have seen the more-amazing Odfrank's post about the swarm in the empty box. I know this doesn't compete. Still interesting.
