VIDEO: Gronk goes trick-or-treating as Master Chief on 'The Late Show with Stephen Colbert'

Rob Gronkowski got into the Halloween spirit in an appearance on "The Late Show with Stephen Colbert" on Friday night, stopping by to trick-or-treat while dressed as Master Chief from "Halo 5."

Though the segment was largely centered around some not-so-subtle promotions of the new video game, host Stephen Colbert made sure to congratulate the New England Patriots' star tight end for "spanking" the Miami Dolphins on Thursday night.
