Turns out, the host was only kidding.
As Harris did at the 2011 Tonys, the How I Met Your Mother star closed out the show with a rap spotlighting the night's biggest moments, this time set to the Jay-Z/Alicia Keys collaboration "Empire State of Mind." (In 2011, he rapped a cappella.)
Audra McDonald performed the rap alongside Harris.
The host also opened the awards show, which aired live on CBS (with a tape-delay on the West Coast), with a big song-and-dance number that featured a cameo by Mike Tyson.
Harris returns as host of the Primetime Emmy Awards later this year.
