My money's on "secret cult," honestly.
Spearheaded by the Ice Cream Truck, obviously.
reminds me of the Popsicle man who would come around our neighbourhood when I was young. The company was Dickie-Dee, he would hand out stickers, I would get the Popsicle that was red white and blue... or the 'ghost' with a nose made of gum, it was awesome...
now my childhood is ruined at the thought of the Dickie-Dee man being a part of a cool treats secret cult...
hahaha!
