She might not be too bright, but in any IQ race, she'd put Pedro Picasso in the shadow.
Well, in an IQ race most anyone, with the exception of poor, stupid Beth and Sheila Jackson Lee, would trounce stupid DUmmy atman.
Poor, addled grasswire may not be entirely stupid.
She's afflicted, addled, not "right", wandering the streets bundled in multiple overcoats, pulling her little red wagon heaped with devil strip detritus, mumbling about the pie shop that will never happen.
Maybe, like the guy from my hometown, she collects hair from the barbershop floor in little medicine bottles.
It's genetic, like Pam Dawson, or Dustin Hoffman in "Rain Man".
In some obscure niche, like years-old Free Republic threads, she may have encyclopedic knowledge.
But she still can't function among normal people.
