one of the highlights of the jimmy fallon/horatio sanz/tracy morgan/chris kattan/will ferrell era of snl was their random decision to write and perform a song called i wish it was christmas today. (will ferrell not included...but that was the era).
apparently the lead singer of the strokes covered the song on his solo album, and he performed it on jimmy's show with jimmy and horatio the other night. if you've never seen the original, watch it first.
