Mike Tyson and Neil Patrick Harris perform in the opening number
And, as if Harris' opening number wasn't entertaining enough, the 'How I Met Your Mother' actor was joined on stage by the one and only Mike Tyson.
The former boxer currently has his own Broadway show, 'Mike Tyson: The Undisputed Truth,' which was directed by Spike Lee and written by Tyson's wife Kiki.
