Josh walks out into the hall, slightly dazed, holding the letter out awkwardly. Margaret sees him from down the hall and says that Leo wants him in the Mural Room. He changes his dazed course and drifts down that way. He opens the door, and sure enough, everybody's there yelling, "Surprise!" They're throwing confetti and bleating on those paper noisemakers. Most of them sing "Happy Birthday," and Jed beams at Josh. Josh can't wipe the shell-shocked look off his face, but he sort of makes an effort. And if you look very carefully, when he opened the door you could see his cake, which is in the shape of a big grey fish. A fish cake. If that's not a shout-out, I don't know what is.
