...reminds me of the _Monty Python's Flying Circus_ sketch featuring the man [Terry Jones] trying to change clothes at the beach:
That's kind of out of the blue...
If you mean Sandy's kind of a prude about getting undressed in front of people, well, duh. I think the vast majority of people are, including virtually all of the TWB cast.
I think pretty much any of our principal characters would act about the same way as in that clip. (Well, at least up 'til the end part, anyway. )
If you mean Sandy's kind of a prude when it comes to depictions of nudity, well, yeah, no duh, again. Here, too, most people are- that "butt shot" would actually make a nice print, but there's very few people out there that would actually hang up and display something like that. In their bedroom, maybe. In the living room, or even in their "man cave"? Not hardly.
