Wait? Festus is Luke Gallows? WTF?

Not to sound like an idiot (i dont follow smackdown as closely as RAW) but i found out that FESTUS was actually LUKE GALLOWS. WOW I never realised it, and was it supposed to be Festuas got turned into Luke Gallows by CM Punk or did they just get Festus to play his role, like he was a new guy.
