No one does Halloween like TODAY, which begs the question: What will the anchors dress up as this year?
For the past 20 years, the show's anchors and staff have worked tirelessly to create memorable themes and costumes for the show's annual Halloween celebration. And 2016 will be no different (though we're not giving any hints)!
To gear up for this year's event on Monday, we're taking a look back at some of the highlights of two decades of Halloween celebrations on TODAY.

2012: There was no Halloween celebration in 2012 due to Hurricane Sandy.
2011: The Royal Wedding

2010: Pop culture icons

Meredith went full Lady Gaga, Natalie caught Justin Bieber fever, and Al and Ann soared as Superman and Amelia Earhart for the year of the icon. TODAY also welcomed special guests Tina Fey and Will Ferrell, who attended the party on the plaza as their "Megamind" characters. See more from the "iconic" TODAY Halloween here.
2009: 'Star Wars'

A long time ago, on a plaza far, far away ... actually, it was just five years ago that the TODAY anchors dressed up as the cast of "Star Wars," covering all the major characters, from Luke Skywalker (Matt) to Princess Leia (Meredith) to Yoda (Hoda, of course). And who could forget those crazy Ewoks? The Force was strong on the plaza that year — check out more photos here.
2008: Fairy Tales

Matt as Humpty Dumpty and Meredith as Pinocchio — what more could you ask for? Well, how about Ann Curry as Cinderella, Al Roker as The Gingerbread Man, Hoda as Little Red Riding Hood, Kathie Lee as the Big Bad Wolf and Amy Robach as Rapunzel? Check out more from the fairy tale Halloween celebration here.
2007: 'The Munsters'
