Teacher: "Oh, we could never lose Banner. He is always growling and roaring at the other children."
I later learned that Banner is REALLY into dinosaurs. Which I already knew, because of the 30 some odd episodes of Dinosaur Train currently on my DVR. Because TRAINS! DINOSAURS! But roaring at the other children? That's new.
(Boys are so weird.)
This video has nothing to do with growling or roaring,
but you can see the outfit in question.
