Jarrett Boykin's Ah-mazing Arms

Green Bay Packers wide receiver Jarrett Boykin has two tickets to the gun show and he's not afraid to take us all there with him.  

Chiseled.

What good is eye candy if it's not useful, though?  My guess is that with those arms, Jarrett Boykin could....

-  do 29.5 one-handed pull-ups.  

-  choke out Walker Texas Ranger.

-  fasten a leather belt around a relaxed bicep, then pop the buckle off when flexing.

-  beat this guy 

at an arm wrestling contest

Which of these are the most improbable?  I'll let you be the judge.
