Feist on Sesame Street

Take kittens, roll them in fluffy bunnies and let them loose in a cupcake store, and it wouldn't be half as adorable as this appearance by Feist on Sesame Street. She looks like she's having a ball, and check out the expression on her face at the end of the clip after the song ends.

Feist announced at Canada's Juno awards earlier this year that the day she spent taping the segment was the best of her life.

"I mean, c'mon please, it's the Muppets we're talking about," she said.

"('1234') brought me two days ago to Sesame Street and it was the Muppets and it was the best day of my life. I'm sorry Junos, but the Muppets trump everything!"
