Some of the smartest people are know look like nutcases - tattoos in all the wrong places.
Some of the dumbest people I know fit the bill of 'June Cleaver' - without the brain.
And then I met my husband and he's slowly working on full sleeves - with skulls, blood and some of the most questionable artwork.
I stopped judging a long time ago. . . I have one on my back which is rarely seen and my parent's don't even know about it.
IQ, though, I believe is irrelevant and meaningless. Just another attempt to classify people according to a crafted test.
