During the Electrical Parade, I was sitting on a curb and the Pinocchio floats were going by. The dancers were the donkey-guy-things, and I admittedly wasn't watching them much, just focusing on the float about to come by. I was a little zoned out, so I suppose one of the dancers decided to wake me up a bit. He came up, bent down, and yelled in my face, "GOTCHA!" and ran away. Despite the lights on his outfit I never saw him coming, I jumped and kinda screamed, and everyone around us cracked up. The other Cast Members gave him high-fives, it was pretty hilarious
Not at the time of course, that guy gave me a mini-heart attack
