I practical joke threads! LOL @ bingo. I can just imagine someone bringing in a lap desk, soft drink, troll doll for good luck, and a big dobber. Might as well play it up. ROFL
These are just jokes:
Someone suggested doing some lawn work before the meeting-put fertilizer in a distinct shape on the front lawn-no damage done but the shape will be a distinct dark green all summer.
Leave a CD player in your coat pocket (or someone else's) with a haunted house tapes and play it with remote control, just for a few seconds at a time so people will think it's their imagination.
Put a tiny piece of tape on the bottom of the faucet in the bathroom. The water will spurt out.
Leave an Ouija board in the library.
Get one of those musical or religious birthday cards. Remove the musical chip and stick it under the carpet so it will go off whenever someone walks on it.
Change the clocks in the kh so the meeting will end early. (I did this in college and it worked repeatedly.)
Tape a small sardine under one of the seats.
Get some vampire teeth and wear them to the meeting, acting like nothing's wrong. If asked, just say you had some cosmetic dental work done.
Make a tie with a scripture citation on it (cafepress.com) that will make them think. Don't quote the scripture so they will be curious and look it up themselves.
Attend the kh cleaning, and be the last person to empty the garbage. In the bottom of the newly changed can, leave an open can of tuna, with the can liner bag on top so it won't be found easily.
Color the hand soap so it temporarily stains people's hands (harmless food coloring, several drops in the liquid soap, or hollow out a bar and insert color. Or cover the entire bar with clear spray paint so it won't later. Or put floral perfume soap in the men's room, then ask the bros afterwards if they're wearing perfume.
Put one of those Christmas window clings in your pocket. Keep an eye on the bathroom so you know when you can have it to yourself. Hang your holiday decoration and close the blinds. No one will see it from the inside.
Make a tiny version of the wt magazine with your copy machine. Plant a smurf on a seat in the library, reading the magazine.
Raise your hand when there aren't Q&A parts in the meeting. Or when you answer questions, do so in a strange voice (Three Stooges, Marilyn Monroe, Felix Unger with a sinus infection, etc.)
Wear full pirate regalia, and keep saying, "Aaarrrrrrrr, I lost my parrot."
Put a little dry ice in a toilet.
Put a lot of lubricant in the lock to the front door. It won't hurt it but it will make everyone's hands all greasy.
Bring hot cross buns to the next service meeting and announce you've brought supplies so everyone can skip breaks.
Take as much litter-ature as you can w/o giving donations. Say you are placing them rapidly but cannot afford to pay.
Put a few drops of yellow food coloring on the toilet seat, or leave a tissue with fake snot on the counter. (Obviously this technique could be applied to feminine products.)
Put a small ad in the newspaper that says, "Free canned goods", giving the address of the kh and listing the time/date to coincide with the next meeting.
If you're single, ask to speak to one of the MS's after the meeting. Be sure to pick a spot where lots of people are within earshot. Tell him loudly that you or your gf is pregnant out of wedlock and ask a lot of questions in quick succession so he doesn't have time to think. When asked to go in the back room, talk louder, but don't move. After a crowd has gathered, say, "Just kidding!"
Find some body makeup that turns your skin into an orangey sort of fake tan.
Walk around smiling nonstop. It is unnerving.
Sing the songs really, really loud, and make up new words like "pedophiles", cleverly slipping them in there so no one's sure if you actually said the right words or not.
Change the discs for the songs so it plays something like Stairway to Heaven.
Leave some furry handcuffs or lube in a chair an elder was sitting in, or better yet, soft homosexual porn.
