She always looks like that to me.
The legendary Mrs. Whiskers was watching Hannity interview the candidates after the debate, paying particular attention to Bachmann.
Her take is that what is wrong with Bachmann is that she has had botox injected right where one's smile dimples would be, causing her face to be a little stiff while talking, and keeping her mouth from smiling when her eyes do.
It makes her look funny [as in, peculiar], quoth Mrs. Whisk.
Cheers!
Collagen (sp?) is injected around the mouth to fill up creases like cigarette smoking leaves. Maybe that is what she did to the sides of her mouth to fill up creases or as I prefer to call them, laugh lines.
Anyone is welcome to come forward and correct me if I am wrong.
