Going to the Burning Man dressed as Mr. Fantastic, the Thing and the Invisible Woman... just wandering around, looking for their "good friend Johnny"... would be one of those weird sideways thing I've always wanted to do, just because it would be funny to me.
The comedy concept that if the Fantastic Four lost the Human Torch, they would look at Burning Man for him... and just never break character? Three of you, just always in character, never actually delineating the premise in so many words that you are looking for the Burning Man at Burning Man.
I'd love that.
It's right along the lines of attending a screening of the Rocky Horror Picture Show, dressed as hardcore Trekkies, possibly even acting "in character" as Starfleet Officers and then... about teeeeeeen minutes in? Just pulling out automatic weapons and spraying the assembled costumed crowd with bullets screaming:
"FREAKS! FREAKS! ALL OF YOU FREAKS!"
I guess the first one's more viable because we still haven't passed that law where the death of Rocky Horror fans doesn't count as a mercy-killing/assisted-suicide but... that's why we live in a democracy, you know? Popular opinion will turn around. Just gotta give her time, that sweet lady Liberty. Just gotta give her time.
