Rudolph

Even the hardest rock and rollers can get into the Christmas spirit, as witnessed by this dangerous cover of 'Run Run Rudolph' from the legendary Lemmy Kilmister of Motorhead, with help from Billy Gibbons of ZZ Top and drummer Dave Grohl of Nirvana and Foo Fighters fame.

Have you ever wondered how Rudolph got his red nose? Well, Dutch scientists have finally explained the mystery. Turns out, the reindeer's shiny nose is the direct result of "hyperemia of the nasal mucosa." Way to take all the magic out of Christmas, science.
