Zwei Steine T-Shirt | Because One Einstein Wasn't EnoughOh, the clever bilingual pun that makes German grammar teachers and physics professors equally proud! This shirt features not one, but TWO Einsteins (or should we say, "zwei Steine"), because sometimes you need double the genius to get the wordplay. It's a brilliant play on Einstein's name, which translates to "one stone" in German so naturally, two of him would be "zwei Steine." This is what happens when dad jokes achieve relativistic speeds!
