Stare Down Sally [1]:

Stare Down Sally: "Stare Down Sally is a simple game. In a moment, you'll meet Sally. She'll be staring at you with a powerful green-eyed gaze. She may stare for an instant...she may stare for several seconds...or she may stare for what seems like an eternity. But eventually, Sally will blink. DO YOU HAVE THE POWER TO STARE BACK... and NOT BLINK?"
