That dude in the seat next to her remembers his first time eating possessed candy... It hits hard if you've never done it before, let me tell you.
Update: The father of the girl in the gif got in touch with me to say that he loved the comic, which is pretty awesome! I think this is only the second or third time I actually got to meet the person who was involved in the gif. She has a twitter too, so feel free to go check out Beatrix Hart for more adorable antics that may or may not involve cotton candy demons!
