What was the deal with that fake Luigi?

Back during the Japan Wii, a dude in a Luigi outfit, handed out the first console and posed for pictures and then got booted in a hurry. But, questions remain: Who was this Luigi? Why was he escorted out? WHAT THE HELL HAPPENED?! The costume was far too good to be an amateur. Moreover, how could this individual have gotten access to Yodobashi Camera. Logic tells us that it had to be an inside job, someone connected with either Yodobashi or Nintendo. The why, the how and the wtf still remain unanswered. An otaku conspiracy, how cute.

My theory......Mario was supposed to show, and Luigi snuck in while Mr. Red Badass was getting frisky with the princess. Oh, Luigi.
