If you take Marios name and substitute the I and O for a 1 and 0, you get MAR10, which is today, March 10th! Thats why today is Mario Day, and Nintendo had tons of exciting announcements for fans, but we got SUPER excited when we heard one of our favorite games is becoming LEGO ized! If there are any Mario Kart fans out there, dust off those controllers and start working out your hands now...
