Rainbow Six: Vegas 2 Easter Egg - Mario Reference

In the level CONVENTION CENTER, play until you get to the MLG area, where you are told to go stealth. In the second room you have to storm, listen, there are two guys talking about video games. One will say "do you play video games?" then the other will respond by saying "yea, when i was little, then i grew up!" The other guy then says "f*** you man games are cool" then the other guy says, "what's the point? a plumber who saves a dragoon." Then the other one will say, "actually it's a princess, whatever"
Funny, Mario is a plumber, and the point of the game is to save Princess Peach.
