A new feature in the Onion A.V. Club, where they ask a slew of celebs their advice to the children of the world. Click here.

It's also nice to see rock luminaries giving both the best and worst answers.

Best - Isaac Brock of Modest Mouse
The Onion: If you could send one message to the children of the world, what would it be?

Isaac Brock: "Grow the fuck up."

Worst - Liz Phair acting like it's the goddamn Miss Universe pagent
The Onion: If you could send one message to the children of the world, what would it be?

Liz Phair: "Play."

O: Play games, play instruments, play what?

LP: Anything. Play, play, play. I'd like to free all the working children. Seriously. It's a horrible thing, as a mom, let me tell you.
