Live from Rockefeller Plaza, it's "Saturday Night Live!"
The morning show team took a late-night turn for Halloween 2014 and dressed up as some of "SNL's" most iconic characters, from the Spartan cheerleaders to Wayne and Garth to the Blues Brothers.
Willie Geist and Tamron Hall kicked off the Halloween Boo-Nanza by channeling Will Ferrell and Cheri Oteri as the peppy Spartan cheerleaders.

Next up: Natalie Morales as Mary Katherine Gallagher. She emerged from behind (Father) Peter Alexander as a "Superstar."
In true Molly Shannon form, she told Peter, “Sometimes, when I get nervous, I stick my hands under my armpits and then I smell them like this!”
