A variant on the famous "Schrodinger's Cat" thought exercise, which questions the living or dead status of a cat locked in a box with a randomly-released toxic gas.

In a Schrodinger's Crap situation, a form of uncertainty principle is applied to certain types of bowel movements which defy pre-emergence classification. It is impossible to accurately predict their state until after it has emerged, by which point it is too late.

Parameters:
1. Something in your rectum is trying to get out.
2. It will be a solid, or a liquid, or a gas. And no other. (No plasmas, etc.)
3. If its final state is gaseous, you can liberate it with minimal concern.
4. If it is either liquid or solid, it will require further steps for successful disposal.

The paradox lies in the fact that the exact state of a Schrodinger's Crap cannot be accurately deduced before opening the system to observation. But opening the system to observation is fatal to the system's continued existence, as the toxic gas is already released. Followed to its logical extreme, the Schrodinger's Crap theory posits that the contents of the system are ALL OF: a solid, a liquid, and a gas - simultaneously.

(Note: the word "uncertainty" also has the word "taint" in it. Coincidence? I think not.)
HMB: Dude, you're walking funny.

HDT: I can't help it. I feel like I wanna fart, or maybe take a dump. But I can't figure out if I'm going to "gamble and lose". I feel like I'm touching cloth.

APLR: Wait, I have an answer. Your digestive system is entirely described by a single state function, "psi". For every observable, "A", there is a corresponding Hermitian Operator, "A^". The result of measuring "A" must be an eigenvalue of "A^". If such an operator has eigenvalue "a" and corresponding eigenstate "phi", then the probability of measuring "a" is the positive value of ("phi"|"psi") all squared. If the result of a measurement of "A" is "a", then the state of the system changes to the eigenstate "phi". Between measurements, "psi" evolves according to the Time-Dependent Schrodinger Equation.

HMB: ...

HDT: ...

APLR: What this means in layman's terms is that the state of your bowel movement cannot be independently observed without opening the system and releasing toxic gases. You have a Schrodinger's Crap situation.

HDT: ... and now I am touching socks.

When you feel a rumbling in your rectum but you'll never know if it's a fart or a poo until you "open the box" by which time the death mass has already been released. Thus, it exemplifies the graceful paradox of the traditional Schrödinger's Cat, yet manages at the same time to make it more accessible to the common person.
1. In order to fart you need to eat, but once you eat you might need to poo instead, so you never can be sure whether you're going to want to fart or poo. This is an eloquent summary of the tragic human condition which can be abbreviated to "Schrödinger's crap".

2. I can't decide whether I want to go to see Harry Potter or Casino Royale. I'll probably know after I sit down in the theater. It's a Schrödinger's crap.
