Some cosplayers take it back to 1993 with their rendition of Lisa and Ralph from “$pringfield (or How I Learned to Stop Worrying and Love Legalized Gambling)“:
Principal Skinner: And now, a special award for those students who obviously had no help at all from their parents, Lisa Simpson and Ralph Wiggum!
[Lisa is wearing the “Florida” costume that Homer made for her; Ralph has a piece of paper with “Idaho” written on it taped to his chest]
Ralph Wiggum: I’m Idaho!
Principal Skinner: Yes, of course you are.
