Bruce Banner said it (in the Avengers movie), it has its own tumblr. page (what doesn't?) and now it's depicted on our Loki's Brain 30 Single T-Shirt! Loki's brain is shown as the bag of cats of which Dr. Banner spoke in the smash hit movie, but you can't "smell crazy on him" as the follow-up line declared. At least not on the illustration of him on this soft, green, 100% cotton, 30 Single thread count Loki t-shirt. Unless "crazy" smells like a fresh new t-shirt. If that's the case you can smell crazy all up and down Loki's profile. We checked. But we won't send you the one we sniffed. We'll send you another high-quality t-shirt from Mighty Fine, who are known far and wide for their superb superhero and pop culture t-shirts.
