Rob Gronkowski on Stephen Colbert show: 'I just love Halloween'

New England Patriots tight end Rob Gronkowski was a guest on "The Late Show with Stephen Colbert" on Friday night, dressed as iconic video game character Master Chief from Halo.

Gronkowski's appearance was tied to a promotion for the new "Halo 5: Guardians" video game released this week for Xbox One.

As part of the lighthearted appearance, Gronkowski poured candy over his head, and defended himself from "criticism" from a young trick-or-treater dressed as a ballerina.
