This is just a great all-around generic Penguins shirt. There's no mention of the Pens themselves, the jerseys are black and logoless, and each of the players only have half of their names mentioned. For the blind out there, Sid is named The Wizard of Croz, Geno is Amazin' Malkin and Marc-Andre is Fantastic Fleury. And as the shirt and my post title say, Malkin is pictured in the middle.
I've never watched an episode of Malcolm in the Middle, so you'll have to let me know if Geno's placement in the physical middle is the only reference to that show. Until then, I think that last paragraph pretty much sums it up. This is a PSAMP-approved unlicensed piece.
