I'm in the midst right now of reading A.J. Jacobs' book "The Know-It-All", an account of his endeavor to read the entire encyclopedia (several dozen pages of it can be viewed here). He mentions the fact that a high IQ is strongly correlated with being able to stand on one foot. I probably wouldn't be bringing this up were it not for the fact that I am able to do this.
The bummer is that there is really only one opportunity I regularly get in which to show this off; not then, you dirty devils. It occurs when one of my shoes is untied. Instead of having to bend down on the ground, like most people, I, while still standing, cross the leg whose shoe is untied across my other leg and string my moccasin up properly.
It'd be cool, if at singles mixers, there was a part at the beginning where everyone was told to stand on one foot. Ladies and gents looking for a highly intelligent lifetime partner could really cut to the chase.
