A Ginger haired actress doing a backward crab walk naked. Lohans only appear during the day. they must be summoned by a husband asking his wife to imagine "L*****y Lohan doing a crab walk naked." the wife must then agree (with no persuasion) and a lohan will apear.
For a better overview of a lohan scenario, see family guy.
