I would like to know what is the funniest practical joke you've ever pulled??? I know there are a lot of pranksters on here..... so lets hear what you'd come up with.

at work, the financial maneger left for a new job, said our goodbyes with cake and all.
then a week later we heard he was coming back.
so Me and the guys went in his office and emptied the whole office but the desk.
including things hanging on the walls
should have seen his face when we told him everyone picked his office clean
the day after he left. He was pissed

A guy at work is absolutely terrified of spiders(me too). I had one of those plastic spider ring things kids get with cereal around halloween. A guy I work with tied the spider to a string, and I snuck up behind the guy, and slowly lowered it down in front of him. I swear to you, I've never seen a 300+ lb man move so fast! He was up and out of his chair screaming obscenities.

I don’t know if you’d call this a practical joke, technically, but it is classy. The kids in the neighborhood like to throw snowballs or waterballoons (summer) at me, or squirt me with their squirtguns. Completely unprovoked, I assure you. The twin girls around the corner found it especially gratifying to drench me. One day I loaded all my Super Soakers, wrapped an empty box to look like a present, and put their names on it. I set the box in their front yard, rang the doorbell, then hid by the garage. Sure enough, they came out of the house like mice from a hole, all giggling & stuff. You should have seen their faces when I stepped around the garage with Soakers-a-blazin’ like Rambo. I practically washed ‘em into the street. It was glorious. Caught ‘em unarmed and unsuspecting. Ahh, sweet memories…

And,

Sometimes, when I have to get up in the middle of the night to let the dog out, I’ll get my camera flash, shake my wife and say “Hey Kim!”, and pop off the flash. That'* a priceless look too. Does that count?

I think the funniest one that stands out in my mind is the old funnel trick:

You take a regular kitchen funnel and put it in the waistband of your jeans. Then you take a quarter and put it on your forehead and the object is to drop the quarter into the funnel. You do this a few times to show your friends how to do the trick. Next get one of the unsuspecting victims, I.. uh.. er mean friends to try and do this trick. When they have their head tilted back to put the quarter on their forehead pour some water down the funnel. It is hilarious, especially at a party since you will have a glass of something in your hand and you can easily have water instead of your drink!!!!

Working at Burger Sling back when..

Store manager didn't want myself or another employee resting on the chair in her office. She sneered at us..said she was locking the door and we wouldn't be able to get in, besides she would be in the booth facing us and could clearly watch us.

Being that all our work was up to speed, we decided we'd sit down in the office as usual. An idea hit us.

30 minutes later the hamburger bun order arrived. She opened the office door and put the slip on the desk where the computer should have been, closed it again and laughed at us.

15 minutes later she comes back, opens the door laughing at us and flips on the light.
Only two things in the office were the shelf with the Musak box and the safe. No desk, no filing cabinet...nothing.

Night manager wasn't happy with us either. He was told to clean and paint the office since it was empty.

The latest was pulled on The Missus by me and my daughter. It was the standard "toy mouse on a string in a cabinet" trick.

The best was when I made my ex-father-in-law a "cake" made out of frosted baloons. When he went to cut it, bang!! Frosting everywhere.

The best one I pulled so far was the "Sold the Bonnie for a ugly Regal" on here. Some may remember, some may not. I'm not very creative at those ****

Ahh, that'* a classic. Someone tried to pull that one on me, but I was too savvy for them and wet my pants before they had a chance to pour water in the funnel. Heh, heh...suckers...joke'* on them!

had a friend staying the weekend at our place and had bought a suitcase of clothes, but forgot to bring his clothes in the bathroom when he showered. there were several people over, guys and girls hanging out in the living room, where the bag was. he came out of the shower with a towel wrapped around him. i reached for the towel but he was to quick and got away.. it took us 3 guys to rip the towel off him... it was the funniest damn thing watching him grab his junk and hi-tail it to the bathroom

i also wrap my brothers x-mas present in duct tape covered duct tape every year... at least a 20 min process that i usually end up helping open.
