Prettyboy often talks about how nice it would be to have a rewind button. He brings it up in the context of things he would do if he did, in fact, have such a button.
A SFW example:
"If I had a rewind button, I would throw this banana cream pie at the stuffy maitre d' to see his reaction." In this scenario, Prettyboy would then be able to hit rewind and the pie would never have been thrown, except in his memory of the event.
I often want a rewind button, as well, largely because I am a big, awkward doofus and I wish I could unsay half the things I've said, untrip all the falls I've made, and unspill all the bowls of cereal/cups of coffee/glasses of orange juice. It's in that reddened, uncomfortable, embarrassed moment immediately following whatever verbal gaffe I've made most recently that I wish against all hope that I could rewind and undo. As a teenager, I once playfully told my Daddio to "shut up," at the outset of the world's longest trip home from a party. He was angrily silent the entire time. Seething. Imagining my punishment. Becoming redder and angrier. And I sat there, helpless, stunned at the intensity of his reaction. So a rewind button, right? Would have been perfect.
What would you do with a rewind button?
