I need ideas!  What are some creative ways that siblings make each
other's lives miserable?  Specifically, what kinds of things can
brothers do to annoy their sisters?  Only funny, creative, practical
joke kinds of ideas - nothing physically harmful or illegal.  Okay if
they're a bit mean-spirited - but not if they could physically injure
someone.

A list of resources is fine OR a list of ideas themselves.  Quantity is key.

Dear lifesize,

Heh heh heh...I love it! 

I located some diabolical resources that should provide you with
plenty of priceless-yet-harmless sibling ammunition. Here are some
great suggestions from a discussion group thread titled "How to drive
one's sibling daft"
( http://www.voicesofunreason.com/fullThread$3494 ):

1. Follow them around and stare at them wherever they go. (Emjay's
note ? mimicking their gestures and repeating everything they say is
also a nice touch).

2. Sing a song to them. Particularly annoying songs when sung over and
over are I am Henry the Eighth I am, Ick Von Schpielman, My Bonnie
Lies Over the Ocean, or The Bob the Foo Song.

3. Continually poke them and jump backwards if they attempt to retaliate. 

4. The silent treatment works if they talk to you at all during the
course of the day. Whenever they say something to you, stick your
fingers in your ears and start chanting "I'm not listening! I'm not
listening! I'm not listening!".

5. Keep saying "Kill the pig cut his/her throat, spill his blood!" 

6. Play the kazoo. 

7. Create imaginary shadow puppet people and tell the offending
sibling that the puppets are crying out for his/her blood.

8. Find some dirty socks and begin rubbing them in the sibling's hair,
jumping backwards if any sort of retaliation is attempted.

9. Continually smack the person with latex gloves (especially good if
they have previously been used to dissect something).

10. If the sibling has any things that they don't want you to mess
with, mess with them. Ie. use their hairbrush or toothbrush.

Another forum member also suggests filling your sibling's water glass
with vinegar for a surprising taste treat. Alternatively, I once
managed to pass off pickle juice as Mountain Dew to an unsuspecting
friend.

Planet Wally's prank archive ( http://gwally.com/pranks ) has a number
of useful suggestions. Here's a sample:

- Punch holes in a can of tuna, then hide it behind a drawer or under
a floorboard or ceiling tile in your sister's room. In several days
she'll notice a stench with no apparent source.

- If your sink has a spray attachment, tape the handle down and point
it in the direction your sister will be standing when she turns on the
faucet.

Placing Saran Wrap over the toilet bowel is always a classic ? stretch
it tight so no wrinkles show, place the lid down and bide your time
until your sister feels the call of nature.

A few suggestions from my own experience ? 

Salt her pop or milk ? it's isn't original, but it's definitely effective

Tamper with her food ? I once camouflaged a layer of plum sauce under
brownie frosting for a special taste sensation

One that never fails to annoy ? if your sister asks "Where did I put
my (blank)?" or similar, reply "Do you feel a sharp pain?" When she
looks at you like you're crazy and says "no," gleefully reply "Then
it's not up your butt!" Do this ad nauseum.

If you've exhausted this list but are still on a roll, try these two

Perfect!  Fast and complete.  Thanks!

When I was 14 years old, my naughty 8-year-old brother found an old
family photo in which I was wearing no clothes (I was an infant when
the photo was taken).

He had the photo copied, and distributed the copies (with my name
written on them) all over the neighborhood.

This doesn't sound very embarrassing now, but at the age of 14, it was excruciating.

Ha!  That's AWESOME . . . now where's that old photo box?  I know it's
around here somewhere . . .

These days I love my fellowman, but there was a time....
 Once long ago I got my hands on a giant spider crab. Quite dead and
dried out. It looked for all the world like a giant spider with long
hairy legs, but only six. My much loved[now] sister in her teens had
the habit of returning from dates and proceeding to her room without
switching on any lights. My [then] ratbag friends and I hung the crab
on string in her doorway at face height. Need I say more. She has
forgiven me.

I am howling with laughter at both the prank itself AND your wonderful
way of describing it.  If you are not a humor writer, it's a
profession you may want to consider!  HA! Thanks!  I appreciate any
and all possibilities.

Anyone with MORE?  :-)

A pumice stone on her pillow with an old shoelace appearing from under
the blunt end looks remarkably like a mouse.
