So I was reading Herve Tullet's Press Here for a class visit (of which, more anon) and it was going over big. I came to a very familiar point in the story:

And from the back of the room, I hear NAME REDACTED chime in with "black and yellow, black and yellow, black and yellow, black and yellow." I don't know what it is about Press Here, guys, but it literally gets the best responses EVER. I had to take a several second breather to pull myself together and marvel at NAME REDACTED's amazing brilliance. What I'm saying is, I love my job.
