Two men were at a bar and one said," Hey, I had my IQ checked and it was 175," The other responded " That's a coincidence, so is mine, what do you do for a living?" " I'm a physicist." was the reply. Again came "that's a coincidence so am I." This was overheard at a nearby table and these two compared IQ's at 160 and were surprised that they were both brain surgeons. At another nearby table one man despondently said to the other "Did you hear that? I had my IQ checked and it was only 52." The other said, rather enthusiastically, " That's a coincidence. So is mine. What instrument do you play????"
