Any water you nonchalantly imbibe after being subjected to a close-range blast from a shotgun will instantly trickle out of the numerous holes left by the shot.
Mice will go to any length to persue cheese. Likewise, small birds will go to incredible lengths to persue worms. Cats will persue both mice and birds with equal effort. Dogs will always persue cats, and will often form a pact with mice/birds which will afford the dog the oppurtunity to chase the cat while the mouse/bird benefits from canine protection. Dogs’ ony natural enemy is the dogcatcher, who wields the deadly net-on-a-stick.

If you really need a ghost to scare someone, but you don’t have a spooky old mansion on hand, all you have to do is cover yourself with flour. No one will know the difference.
Skunks don’t release musk when threatened, they always smell bad. In fact, skunk stence is so powerful that is will cause flowers to wilt, grass to die, and birds to drop from the sky. Skunk stench is easy to see coming, as it exists as wavy, green lines. Should you expect skunk exposure in a friend, look for the tell tale signs of rigidity and greenish skin tone (not to be confused with motion sickness, which results in limpness and greenish skin tone).
Henchmen are always mindnumbingly stupid, which ends up ruining their boss’ plans. Any flashes of insight they may have will be ignored, resulting in the same outcome.
Whenever there are two sides engaged in a laser-gun shootout, the lasers will be color coded to make it easier to identify friend from foe.
Corollary: laser weapons always propogate at sublight speeds, allowing them to be dodged.
