Tim Urban might've gone home - too bad, he was adorable! - but the rest of Wednesday night's Idol Gives Back special was pretty uplifting...

A whole slew of celebs got involved, including Victoria Beckham, Ben Affleck, Jim Carrey, Russell Brand, Jen Garner and, yes the Octomom. Even President Obama and his wife recorded a message of support, where the Prez quipped, "As Randy says, you're all my dogs."

Elton John, Fergie, Alicia Keys, Carrie Underwood and Mary J. Blige performed, and George Lopez turned the tables and poked fun at the judges! Best line? He said he's "always wanted to ask this one question of you Simon Cowell - saline or silicone?" Loves it!

Sounds like an emotional night, except for Lopez's quips!
