MLG is going to win the immature contest, cause he gots my vote.
ear614 however sadly i dont know who is younger than 14 but thank you for being mature compared to some people cause i wouldnt have guessed ur age, so what country or state you live in?
MLG makes a point. he isnt really immature (for his age). he is conceited, stubborn, and rarely tolerable (not much different than myself actually), but he is not immature. :)
