“Grunhilda’s Stink Eye (a.k.a. Grunhilda’s Hairy Eyeball) has given me the confidence I need to control almost anyone with nothing more than a dirty look. Bosses, teachers, and members of the clergy have been using it for decades to express firm, but silent disapproval. Thanks to Grunhilda, parents of the ill-mannered can save their lungs and yell with their eyes.”
