What's the big idea, Squirrel?

I confess. I love the Dilbert comic strip. Everything about it, from Dilbert himself to Ratbert and all the other little creatures that show the sad but funny truth behind modern corporate existence.

Today's strip, however, gets a bit squirrelly. The Idea Squirrel shows his furry head, and Scott Adams, the strip's creator, demonizes the Idea Squirrel as a villain:

The Idea Squirrel, he notes, steals your ideas and makes you feel like a nut for claiming the idea as your own.

Ah but Mr. Adams, squirrels have enough ingenious ideas. They don't need to be stealing a thing from us humans except, of course, the nuts we spend our hard-earned money on so we can then toss them at the squirrels in our yard and smugly think this is all OUR idea.

Of course it's not - not by a long-shot. The squirrels have simply manipulated us into thinking the idea was ours.

Differences of opinion aside, Mr. Adams, let me commend you on a gently funny strip anyway. It was, I must say, one of the best ideas I've seen lately.

Only one question: What squirrel did you steal it from?
