Weezer appeared on David Letterman’s show last Thursday (Oct. 29), and they repeated the trick the following night by returning to the show to perform “I’m Your Daddy.” The talk show host even manages to get a few cracks in about the Weezer snuggie, which is available on their official website.

The band and Paul Shaffer all don the snuggies for this performance of “I’m Your Daddy,” which is taken from the forthcoming Raditude. The song features the usual mix of grinding Weezer guitars and bouncy vocals from Rivers Cuomo, with the addition of a horn section and, bizarrely, a group of kids clapping along.
