It’s three of my favorite things combined:
ModCloth, T-shirts, and rocks. I don’t even know what to do with myself. I’m already trying to identify all of them. My little nerdy heart flutters at this sight of this. It makes me want to … yes … make rock puns, like in the title (gneiss is a type of metamorphic rock). But don’t worry, I won’t take your readership for granite by basalting you with schist-y puns.
Okay, sorry. I couldn’t help myself. I’m done now.
