I thought a lot about creating these "thinking caps"...but it turned about to be a big hit with clients and friends-in and out of the marketing business. Two reasons, i "think": 1)people love short-cuts and if you can simple put on a thinking cap and not have to really think-it's a "no brainer". And, 2) most of us have been told by teachers, coaches, parents, etc. to put on "your thinking cap"...to be able to actually do it (and maybe show them up alittle), well, that might just "cap" it off! Oh, yeah, one other possible reason for their "demand"...they were always FREE!
