Ok, confession time: I don't have kids and I've never seen an episode of Yo Gabba Gabba, but I am a big fan of some of the bands who've performed on the show.
Here are a few of my favorite Yo Gabba Gabba videos:
Flaming Lips - "I Can Be a Frog"
Paul Williams - "Rainbow Connection"
MGMT - "Art is Everywhere"
The Shins - "It's Ok Try Again"
The Roots - "Lovely, Love My Family"
Of Montreal - "Bananas, Rice, Applesauce, Toast"
The Aggrolites - "Banana"
