Think ant foraging. Drop something on a counter top, and eventually the ants are going to find it. 100 other ants went out looking and came up dry, but that one ant, finds the crumb, and leads ever other ants back to it.

It's funny how that one ants never run out of battery before he can get back and tell his story. It's not like they can call a tow truck if they break down on the way back home. And I don't think they can shout out, hey down there, can you hear me, I'm out of gas up here.
