The TMI guys ring in the holidays — and Jordan's birthday! – by going deep into 10 of their favorite (or, in some cases, least favorite) Christmas songs. You'll learn how that mind-melting David Bowie-Bing Crosby duet came to be (as well as the morbid events that followed) as well as the hilariously drunken shenanigans that unfolded on the set of Wham!'s "Last Christmas" video — plus the saga of George Michael's hair. Heigl shares his passion for jazz through the Vince Guaraldi 'Charlie Brown Christmas' soundtrack, in addition to the hilariously fast genesis of "Feliz Navidad" and the precocious brilliance of Brenda Lee and her deathless "Rockin' Around the Christmas Tree." And whatever you do, don't miss out on Jordan and Alex's battle over whether or not Paul McCartney's "Wonderful Christmastime" actually sucks. Merry Christmas to all, and to all a good fight!
