Would You Rather?

I thought of this one in class. I'd love to hear thoughts:

Would you rather have the power to lightly zap someone when they're doing something annoying, or a tiny button on your abdomen that, when pressed, made the urge to pee go away for another 3 hours with no health risks?

Zap:
Pros include getting out your anger as well as training people to behave better in public. It's just a little zap, like the electric shock you might get in winter when touching a metal door, but it could condition people to quit their behavior if used wisely. For example, the guy on the train clippity clippin' those nails behind me? Clip ZAP. Clip ZAP. Eventually he puts two and two together and stops clipping for the moment. The annoying women who sit behind me in Research Methods and whisper constantly? Whisper ZAP. Whisper again ZAP. You get the picture.
Cons, for me at least, are minimal, BUT we have to consider that I might take too much pleasure in it and become a full-out sadist.

Pee-Control Button:
Pros include never having to race to beat the line at intermission during a show- you've got another three hours before you need to go! You can comfortably enjoy an entire baseball game or avoid a skanky bar bathroom. Long car trips can be planned to avoid stops, since you pee when you eat or get gas, never in between. No constant peeing when out on the town enjoying drinks. Never having to pee in a bush.
Cons include having a ridiculous button to explain to the man or woman you take home after meeting them at a bar and enjoying a blissfully uninterrupted 3-hour talk-and-flirt fest. And people thinking you are a robot. Or have really concentrated, goldenrod-colored pee.
