The Funniest gamertag Would Be Mine Of Course. It Was "Adirtybutthole" On Regular Xbox. Then I Got My XBOX 360 And Had To Change It To "Adirtybutthol3". Then They Made Me Change That Due To Code Of Conduct So I Changed It To "stdeeeez" Then They Made Me Change That Also. So Currently My GT Is "std3333Z" The Reason I Fond Mine So Funny Is Because When I Kill Someone It Says You Were Killed By (adirty6butthole,Std3333z)On There Screen....That Is All . Try to Flame Me If You Wish ,But My Gamertag Is Ther ISh.
