I was thinking after I posted that -- Aren't a lot of superheroes wearing their one-piece costume under their normal clothes? How are they going to the bathroom? Spiderman, fine, he made that himself. Batman? He's got armour now. Newspaper headline: Bruce Wayne shoots himself while using the toilet. But Superman... He's got it rough. His suit doesn't break. Superman would have to take the entire suit off just to use the bathroom, and that's just No. 1. (I imagine Superman must be pretty pale if he's always got a long-sleeved shirt on). They must have it figured out. I imagine at some point someone must have said, "Hey! Is that a bum _____-ing over there?" and someone else would say, "No, that's just (insert superhero character). They had an emergency." I've only been thinking of male superheroes too. That situation would come up as soon as they put on the suit. If you are ever aware of a superhero flying over, you might not want to look up. But if you do, don't open your mouth.
What if... you took two keyboards and tuned the second one up or down 50 cents? what if you stacked the keyboards on top of each other? Voila! Quarter tone instrument.
(Bob is still picturing Batman gearing up with all his amour, then pausing for a second, then quickly removing all his armour again and hurrying away.)
