To start, the Live! with Kelly and Michael hosts goof around in the clip, jumping in and out of a remaking of the video, as well as cameoing characters from other popular TV show spoofs such as Madmen, Downton Abbey and Orange is the New Black.
Eventually, others get in on the silly fun, including Hugh Jackman, Tina Fey, Anderson Cooper, Matthew Broderick, Kerry Washington, Luke Wilson, Mario Lopez, Sofia Vergara, Ted Danson, Emma Stone, Josh Groban, The Walking Dead‘s Steven Yeun and Lauren Cohan, and even Bill O’Reilly. Oh yeah, and even Swift gets in on the fun.
