When exaggerating for comedic effect, it’s important to find just the right level of exaggeration. Our brains automatically filter out information that is too far removed from the credible, with ruins the effect. You have to get the listener to actually consider the plausibility of what you are saying for just a moment, and not just immediately dismiss it. In his review of the new Transformers movie, “Revenge of the Fallen”, Charlie Jane Anders writes:
The closest thing I can think of to this movie is the Wachowskis’ “Speed Racer”, which had a similar kind of CG image overload, although it was only five hours long as opposed to ROTF’s nine.
If Anders had used 500 and 900 hours, instead of 5 and 9, there would be no joke.
With art, you can cut even closer to the edge of plausibility, and the effect goes from comedic to disturbing to funny to sublime.
Shown above is “Martinique”, by artist Cristina Vergano.
So, I’m not sure what you are getting at here because I find zero comedic effect here. I mean whatever the artist is trying to convey completely escapes me. Martinique is a a small tropical island whose natives are of french decent, creoles through and through. Everytime I encounter the image of an armadillo I think of Texas roadkill. The link here is beyond veiled. While a bit intriguing to see an armidillo at breast it is not even vaguely amusing.
I would suggest it is surrealism (dreamscape symbolism etc) rather than humor.
Interesting though.
