"I start thinkin' about my Bonnie from the minute I wake up, and that feelin' is the best I ever had. She is in my shaving mirror, she is in my coffee cup. I must be in love or else I'm going mad." When monster hunting brothers Sam and Dean Winchester stumble into a roadside diner after closing a case, they find themselves enumerated by their red haired waitress - Texan sweetheart Bonnie Walker - and can't seem to find a remedy for their infatuation.
