"I've done it! I solved it! But it only works for a spherical chicken in a vacuum."
Q: Why are quantum physicists so poor at sex?
A: Because when they find the position, they can't find the momentum, and when they have the momentum, they can't find the position.
Nah, too much certainty. "There existed, a short time ago, in a place that appeared to be Scotland, an object that appeared to be a sheep, which appeared to be black on what appeared to be half of it."
Don't go away! I got another one!
Guy hears a knock on the door and opens it. It's Schroedinger, who asks "Can I borrow your cat for an hour?" The guy says OK and hands over the cat. An hour later Schroedinger brings back the cat. The guy takes a look and says, "What have you done to my cat? He looks half dead!"
The problem is that the cat is not half dead. It has a 50% probability of being 100% healthy. The other 50% probability is that it is dead.
This quirk inspired a professor of mine who wrote the relativity textbook* that we used in class. The first chapter was a review of Newtonian mechanics and included a problem involving a 2-horned African Rhinoceros charging into a ball of putty on frictionless sheet of ice, in a perfect vacuum.

My physics prof at Clemson once gave us a similar problem, but it actually involved a chicken in a vacuum. We were told to assume that the chicken was a sphere at the end of the problem. Physics humor, eh?
For certain values of spherical, this is true. Topologically, a chicken is a messy doughnut.
