Okay, so there's two possibilities with this video: either the prank above is very much a fake, or the man on the other end of the phone is the most gullible Domino's Pizza employee in the world.
Then again, we've seen that previous Adele-themed pranks have worked, so maybe the guy just hasn't listened to "Hello" yet.
A British YouTuber who goes by the name The Unluckiest British Bloke Ever (and who, judging by his channel, is definitely not new to the concept of prank calls) is the man behind the scheme.
