Penn State alum Keegan-Michael Key (of Key and Peele) is slated to be the grand marshal for Penn State's homecoming, and since he was in town, he decided to drop in and have a little fun with the football team. Doing a little "fliperoo" on the players, Key swapped places with Penn State's head football coach James Franklin, and it even took the team a couple of beats to realize that anything was different—Key is that much of a dead ringer for Franklin.While Key fumbled the voice impression, his mannerisms weren't too far off, as he paced the floor, and made players read Mother Goose rhymes. He nailed the handshake and even threw in a "it's going to be here before you know it" for good measure. Now both Key and Franklin have the easiest Halloween costumes ever.
