'Twas brillig, and the slithy toves did gyre and gimble in the wabe

We got a deconstructed foam cube some years ago. It had letters on each side, spelling out THINK. I can't remember what was on the sixth face, although I do remember thinking that the rubbish idea was rendered even more rubbish by the fact that they were using a six-faced shape to spell out a five lettered word. We also all got baseball caps with "thinking cap" on them. The media mocked the whole thing mercilessly, and it reached the national press, IIRC.
