If you're pissed, that means you had to arrive at the state of pissed. So at some stage, you were pissing.

Logically, unpissing would help you revert. And if experimental dance helps the urine go back in, it can't be a bad thing. Although it probably cooled down in the interim, so it could be a bit of a shock, which could lead to being pissed again. So you could have a quantum superposition of both pissing, and reverse pissing.

Physics and interpretive dance is where it's at, kids! The forefront of science! Thanks impissed.net!
