I found out last night that I am immune to bicep crushes due to having 2 'Matt Serra' biceps. So that's the Duda and arm crush from spider web I don't have to worry about. If you want this super power, you just have to snap 2 tendons on each arm. So next time you are caught in a tight armbar, tap on the sound of the 2nd pop and once the swelling subsides and the bicep eventually shrinks to half its original length, you too could have uncrushable arms in time for Christmas - you know you want to.
