I know similar jokes like this one have been made, but I think this is the first comic of it.
Immediately when I saw that scene in today's episode I thought, "Derpy's eyes are naturally dizzy, she could fly perfectly after being spun around." Plus I couldn't have been the only one to think that the Dizzatron looked like a roller coaster ride.
