Generally, holiday spoof songs are pretty bad. Are they ever really as good as the original songs? Well, this video of Jimmy Fallon, Rashida Jones and Carrie Underwood might just change your mind. The singing trifecta rewrote popular songs like Katy Perry's "Roar" Robin Thicke's "Blurred Lines" in honor of the holidays. Topics they replaced the original tunes with? Black Friday, Christmas and that sleepy feeling you get after consuming too much turkey.
