Everyone knows Pittsburgh Steelers Safety Troy Polamalu for one of two things, either his hard hitting on the football field or his beautiful long hair. Yesterday that may have changed when a few of Polamalu's teammates snuck into his trailer and pulled a "Jackass" type prank on the Pro Bowler. I'm still not convinced that it's real (like Kobe jumping over a moving car) but Troy plays the part well if it is. Check out the stunt below and let me know if you think it's real or not.
