Last night on Late Night, two SNL besties reunited and made for such cute, happy TV. So for that, thank you, Jimmy Fallon and Amy Poehler, who scratched out a note for her Parks and Recreation BFF and tomorrow's guest Rashida Jones, then snuck it in the chair so Fallon wouldn't read it. She then ad-libbed a march song for her Golden Globes co-hosting gig with Tina Fey — "Lower your expectations, Lower your expectations" — and completely fangirl'ed over her celebrity crush and P&R cameo Joe Biden. Plus: Joseph Gordon Levitt received texts from "Abraham Lincoln" when he was still Daniel Day-Lewis, but as filming drew closer, DDL wrote him a hand-written letter — with a fountain pen. Also, David Letterman, unsubtle hater of tattoos, teased Scarlett Johansson for her newest lucky horseshoe tat — "So, you're a Colts fan, huh?" — and Alicia Keys crooned a sexy blue light version of "Girl on Fire."
