Modest, self-effacing, “who, me?” parents in the audience, humbled. “Put a smile on your face…have fun,” etc. The idea is that Fallon’s new, Manhattan-based Tonight show will take most if not all of the under-45 viewers and that Late Night with David Letterman can have the rest. In that time slot. Possibly. Maybe. We’ll see. Good opening, in any event. Will Smith is over, but Seth Rogen, Robert De Niro, Tina Fey, Seth Rogen, Lady Gaga, Mariah Carey, Rudy Giuliani, Lindsay Lohan, Stephen Colbert and…like that. Reactions?
