Prank

Pranks are an interaction where one Sim uses physical humor to amuse— or annoy — another Sim, or an interaction involving objects. They were first introduced under that name in The Sims 2: University, though some of the abilities Sims could gain from Crystal Clear Ability Rocks in The Sims: Makin' Magic are essentially pranks.

Pranks are reportedly set to be re-introduced, however, that will be seen in a different form, in The Sims 3: Generations expansion pack.

The Sims 2
The Sims 2: University introduced 3 types of prank that one Sim can pull on another.


 * Ventrilo-Fart - The prankster will break wind and blame it on the victim, causing major humiliation if in a public place.
 * Joy Buzzer - The prankster will shake hands with the victim, and electrocute them. This does not result in death, and is more or less harmless to the victim.
 * Water Balloon - Pretty straightforward, the prankster splashes a water balloon on the victim's head. A puddle will form under the victim

Pranks can have a positive or negative effect on two Sims' relationships, depending on how high it is. For example, if a Sim's good friend pulls a prank on them, the outcome will have a positive effect on their relationship. When a Sim's enemy pulls a prank on them, it will have a negative effect on their relationship. The same counts for acquaintances - the higher the relationship, the higher the chance of a positive effect.

There are also pranks which involve objects.


 * Fire sprinkler prank - The prankster will take out a lighter and put it under a sprinkler, causing it to go off

There is also an additional prank called Static Shock, available only to children (though mods exist to enable it for other life stages). To do this, the child must be standing on a rug. They will rub their feet on the rug, walk to the prankee and touch them with their finger, causing them to act as if they had been Joy-Buzzed
 * Soap in fountain prank - The prankster will take out a box of soap and shake some into the fountain, which will cause the fountain to have bubbles coming out of it.

The Sims 3
Pranks were not included in The Sims 3 base game, but are reportedly set to be added in The Sims 3: Generations. A game trailer shows a number of pranks, including a Sim lighting off a "stink bomb" in a library.
