Mt favorite is one I heard of when I worked in ad agencies in the late sixties. It concerned a guy in a New York ad agnecy twenty years earlier than THAT, which was before JFK put an end to men in suits wearing hats.

The man was a self-important type, and one day he came back to teh office with a custom-made hat which he bragged about. Several employees chipped in, went to the hatmaker and bought two more hats exactly like it, only one was a couple sizes smaller, the other just as much too large.

All three hats had identical labels on the inside, which had even had the guy's name on it.

Obviously, the joke was to substitute one of the non-fitting hats for the right one and keep switching them around -- mixing the original in, too. It's not hard to imagine what it looked like or, for that matter, what must have gone through the guy's mind. I am not sure how it came out.

I do not know if this story is true or not, but I diod hear it in the late sixties from a co-worker who would go into my boss' office every day when the boss wasn't there and give the height-adjustment knob on his chair a quarter-turn.
