Eighteen of them over at Borepatch - here are the first five:
1. Law of Mechanical Repair - After your hands become coated with grease, your nose will begin to itch and you'll have to pee.
2. Law of Gravity - Any tool, nut, bolt, screw, when dropped, will roll to the least accessible place in the universe.
3. Law of Probability - The probability of being watched is directly proportional to the stupidity of your act.
4. Law of Random Numbers - If you dial a wrong number, you never get a busy signal; someone always answers.
5. Variation Law - If you change traffic lanes, the one you were in will always move faster than the one you are in now. This is also true when you change checkout lines at Walmart, K-Mart and the
Grocery store.
So true - thirteen more at the site.
#1 always gets me - it is close kin to the joke about how you can tell a machinist - they are the ones who wash their hands before they go to pee...
