Because No One Ever Regretted Having Good Lubrication T-Shirt. The T-Shirt only offered in grey, sixe XL for showing off Developing Competency with the Highest Possible Standards for the Best Possible Use in terms of lubrication. Seriously, did anyone ever regret good lubrication? I DON’T THINK SO!!! Its a high price to pay for a T-shirt but hey, what can we say…we develop competency we really know nothing about T-shirts!
