The Miz is Used to Being Booed by Crowds of People
As someone who doesn't watch the WWE, I find it very hard to see Mike "The Miz" Mizanin as anyone other than that guy on The Real World: Back to New York. Regardless, he appeared on Conan and brought a lot of attitude.
After, he made fun of the name CoCo and gave him some new options, including "the red-headed mess of TBS" and the "ginger ninja."
