A Los Angeles area woman named Karen ingeniously used her recently purchased Nintendo 3DS to catch her cheating spouse.

Karen’s husband apparently purchased two Nintendo 3DS consoles; one for himself and the other console for his mistress. Karen presumed that if the mysterious women came over to their apartment then she would carry her Nintendo 3DS with her. So she subsequently purchased a Nintendo 3DS and left it in the closet, hoping to catch whoever the women was via the 3DS’ Street Pass mode.

“I read online that the 3DS was going to have this Street Pass function, and it would allow your system to hook up to another person’s system. So I secretly bought one.”

“I came home from work yesterday and saw nothing, but on April 1st, my 3DS’ Street Pass was lit up and saw the bitch’s Mii on it.”
