This a hundred years from now. Due to the continuing process of evolution, plus mutation, plus toxic waste, plus some genetic experiments that went bad, squirrels are in charge. Humans are second and just a little ahead of crickets.

"That guy's a little squirrelly", one says.

"Uh, we all are, idiot", replies the other squirrel.

Humans are used to gather nuts for the squirrels. It's about all they are any good at. When the changeover became noticeable scientists were saying things like, "This is nuts!".

"No, it's a computer", was the reply from the squirrels.

"No, I mean, squirrels are only rats with bushy tails", the scientist explained.

"Shh, they don't know that. We don't want to get them all riled up", the scientists would say.

"We hunt squirrels", the outdoors guys would offer.

"Not since we started shooting back", the squirrels would tell them.

"Ah, ha", one biologist was heard to say. "You won't get around this. We have an opposable thumb. You don't."

"Yea, that's true. That's why we are taking over. You and your damned opposable thumb makes it easier to gather the nuts".

No human had an answer to that.

Squirrels rule!
