Hey O'Reilly: Fight your War on Christmas—just don't drag talented and adorable Neil Patrick Harris into it! Tonight, O'Reilly ragged on a Frosty the Snowman-themed promo for "How I Met Your Mother". "Pathetic!" cried O'Reilly's guest-bag.

Dang, only Bernie Goldberg can make criticizing people for pathetically trying to be hip seem less cool than people pathetically trying to look hip.

(Our e-pals at Gawker.tv pointed out the pretty funny "HIMYM" promo a while back: watch the whole thing here.)
