The zoo takes special care to keep kings separated from opposite-color pieces as part of their conservation program to prevent mating in captivity.

You don't want the nitrogen percentage to be too high or you run the risk of eutrophication.

I don't dig pit traps and cover them with sticks and a thin layer of leaves nearly as much as I expected; I find a chance to do it barely once a month.

You may notice the first half of these instructions are similar to the instructions for a working nuclear fusion device. After the first few dozen steps, be sure to press down firmly and fold quickly to overcome fusion pressure.

The most important quantity for meteorologists is of course the product of latent pressure and temperostrophic enthalpy, though 'how nice the weather is' is a close second.

Inside is a third box, labeled DO NOT OPEN UNLESS YOU ARE IN THE TIME ZONE WHERE YOU OPENED BOTH PREVIOUS BOXES.

I still don't know how the police found my compound where I ran an illegal searchlight depot/covert blimp airfield/fireworks testing range.

C'mon, ESA Solar Orbiter team, just give the Parker probe a LITTLE nudge at aphelion. Crash it into the sun. Fulfill the dream of Icarus. It is your destiny.

Under some circumstances, if you throw a D8 and then a D12 at an enemy, thanks to the D8's greater pointiness you actually have to roll a D12 and D8 respectively to determine damage.

Fermions are weird about each other in a standoffish way. Integer-spin particles are weird about each other in a 'stand uncomfortably close while talking' kind of way.

Even when you try to make nice, smooth ice cubes in a freezer, sometimes one of them will shoot out a random ice spike, which physicists ascribe to kiki conservation.

In the aviation world, they don't use AM/PM times. Instead, all times are assumed to be AM unless they're labeled NOTAM.

It works because a nautical mile is based on a degree of latitude, and the Earth (e) is a circle.

No, of course we don't microwave the mug WITH the teabag in it. We microwave the teabag separately.

The growth rate of items per day may may seem absurd, but it's actually much less than the acceleration in the 12 Days of Christmas song.

Hmm, they won't do in-flight delivery, so let's order a new first and second stage to our emergency landing site and then try to touch down on top of them to save time.

We also should really have checked that the old water tower was disconnected from the water system before we started filling it with compressed air.

Look, you can't complain about this after giving us so many scenarios involving N locked chests and M unlabeled keys.
