*warning - this is really mean and sort of demented, but funny.

Create pond.

Create island of one square.

get cheat to be able to move your sim manually.

place sim on island.

build walls all around sim.

Watch sim squirm.
(optional - after building walls, set a square directly beside it and place a gas stove on it.

Wait for the comedy.

PLEASE NOTE guys i would NEVER do anything of this sort in real life.

For me thats what video games are - a way to do silly nonsensical and even "evil demigod muahaha" type things.

ever have a sim get trapped at your house, like a visiting one? they cry and whine and complain and pee themselves and starve.
