If you watched season 2 of Atlanta on Fox there was one episode that stood out more than the rest, and that is the episode with the very weird character Teddy Perkins.
In the episode Donald Glover himself was made up to be Teddy Perkins. (NSFW clip below)
So when people saw Teddy Perkins in the crowd at The Emmy's last night, they assumed it was DG.
But then there was a pic snapped with Teddy and DG in the same pic!!!
The mystery seemed to be solved later when rumors surfaced that comedian Jay Pharoah was actually the one dressed as Teddy. Jay also posted the pic on Instagram, and numerous sources claim it was Pharoah as well.
