If you have access to someone's house, there are literally thousands of
things you can do to make someone think that they are losing their mind.
Relocate common household objects to strange places.
This is expecially effective if the person does not know that anyone else
has been in their house. Don't randomly throw things around, but each day,
move a few household objects to uncommon locations for these objects. Place
the TV remote in the refrigerator. Place several hard-boiled eggs on the
fireplace mantle. A can of Pepsi in the kitchen sink. A single shoe on
top of the television.
Stick blank sticky notes to the mirrors, refrigerator, TV and computer
When the owner of the house leaves for a few hours in the night or evening,
run in there and turn on every single light in the house. After
a few nights this can get very confusing to the person, who's sure they
turned 'em all off before he left.
If you can get into their car, slide the seat all the way back or tilt
it all the way back every chance you can. -Peter Trench,
If you can get into their house, too, take something out of their houseand
put it in their car (food from the fridge, shoes, the TV remote, anything
else) -Peter Trench
If you cannot get into the house, there are fun things you can do with
the answering machine:
Slowly read a list of random letters numbers, etc., pausing between each.
(Ex: K. Two. L. X. C. V. Charlie.
Seven. Dishwasher. Q. Seventeen.) Then hang up.
Make a recording of this person's outgoing message. Call the machine repeatedly
and play it back. Alternatively, you can play back a tape full of other
peoples' outgoing messages.
Well, that's all we've been ambitious enough to post so far. Have any good
ways to drive someone straight to the sanatarium?
