For every jabroni committing the cardinal sin of using NFL Shop's custom jersey feature to put their own names on a jersey, there are heroes like this man who come around and use it for its real purpose -- subtle trolling.
Using Tom Brady's number 12, the jersey references the equation for the ideal gas law (PV=nRT), which of course, is cited in the argument that temperature was responsible for under-inflated footballs in the AFC Championship Game, rather than a shoe recipient known as 'The Deflator' who threatens vengeance in the form of "fucking watermelons coming."
For a quick primer on ideal gas law, P represents pressure of gas, V represents volume, n is the amount of substance (measured in moles), R is the universal gas constant, and T is the gas temperature. All these years later, those high school chemistry classes are starting to pay off.
I'm just about as sick of the Deflategate nonsense as anyone else is, but when a jersey like PV=nRT comes along, I can't help but appreciate it.
