Law of pi 

In engineering, every task will take exactly 3.141592 times as long as initially anticipated. The Law of pi is therefore commonly used along project managers when they ask engineers how much time they think they need to finish their work.

Arjan: How long will it take you to finish the design of those tubes?
Vincent: about one and a half hour I think
Arjan: OK, so taking the Law of pi into account, that's gonna take you exactly 282 minutes

Strong's Law of Pizza

In any setting where two or more pizzas are ordered and one of them is vegetarian, it is an irrefutable observation that the leftover pizza is always vegetarian.

Associated Findings:
- People always over-estimate how many vegetarians are in a setting because they are so vocal about their habit
- Vegetarians don't eat much
- Vegetarians will eat the cheese pizza because it is meat free

I was starving this morning and dying for leftover pizza from the party. Sucked because all that remained was the terrible vegetable pizza. Strong's Law of Pizza

PS - Dear editor, try this out. Buy pizza for your staff. Make one in three vegetarian and if I am wrong about what is left over send me a note and I will pay the pizza bill. Guaranteed!
