Best prank you've ever done? (in Contests)

I'm sitting here bored out of my mind at 2:45 AM in my dorm room thinking of ways to entertain myself. Usually in times like these my roommate and I would do something to our neighbor...like duct tape their whole door...but we need something new.

So this makes me think...what's the best prank you've ever done?
500k to the winner.

roll up those little foil ketchup packages and put them under the 'legs' of the toiled seat where they rest on the bowl...

you may want to tape 'em in place, but someone sits down and ~SPLAT~ ketchup on the legs and pants

we took our friend who was passed out on one of those flat lounge rafts in the grass and gently picked the raft up and placed it into the pool. Pushed him out into the middle, then set off an air-horn.

Don't pass out on something that floats, when you're next to a pool >:]

I gave a fake arrest warrant notice to friend with unpaid parking tickets. Hilarity ensued. >;)

I've got toilet pranks ... instead of ketchup under the legs put those fourth of july poppers under them, I've also put shrink wrap over the bowl so when someone peed it splashed every where. You can take and stretch sandwich wrap over the door frame where your neighbors face will be when he walks out so he gets a face full of plastic wrap. Slide some fire crackers up under the crack in his door (if there is one) That's just a few, I'm sure I've got more for dorm/bedroom purposes but if you want pranks in general let me know cuz from age 6 till now (20) that's just about my favorite pass time lol.

Either ask your girlfriend for some transparent nail polish (the clearer and stronger the better), or if that's not an option get your hands on transparent superglue.
Cover all metallic ends of ALL power plugs in the house with a thin, smooth layer of it, so it does't easily show, but won't come off just by plugging them into the wall socket.

Sit back and laugh as nobody is able to make any plug-in electrical appliance work.

do this to anyone who is taking prescription drugs.
Phone him from an unknown number and Call your self doctor such and such from the such and such institute. He needs to stop taking them imiditately and if hes taken more then x amount he should go see a doctor immediatly. Then also direct him to a lawyers phone number that is handleing the tainted drugs for sueing the prescription drug for illness and deaths. Helps if its a friend of yours that he does not know instead of you as he may recognize your voice.

When someones asleep at a party, put 2 small blocks of chocolate down back of there pants.

It then melts, they wake up and feel it and think they've done something ;) and scurry off to the toilet!

ok so i didnt pull this prank but i witnessed it. i was at a fraternity party and i was talking to a couple of the members. after a while they started to wonder what happened to a friend of theirs and i told them i saw him go upstairs with some girl. they were like "ahh no wonder he has been gone a while." after about another ten minutes or so the friend came downstairs and started to talk to us. he said "man i just cant handle this chick....hey jayson why dont you go upstairs and finish her off for me?"

jayson said "what???"

the guy answered "yeah the lights are off just go up there and dont say anything and pretend you are me."

jayson said "ok...see you guys later."

after about ten minutes the other friend started to laugh histerically.

we asked what was so funny....and he said.........

guys i was up there with jayson's sister......this is not made up

they left school the next day

Eww, some of these "pranks" don't even deserve that kind of name.
Pranks are meant to be somewhat mean-spirited, sure, but not cause serious damage of any kind, be it physical, emotional or financial.
That "sister prank" was beyond the moral event horizon, no matter how you put it.
On second thought, let's not even call those things "pranks", but "crimes".

Can we please not even MENTION pranks that could end up into serious damage of any kind from now on ?

I have to agree with Sickone.

guys, Gun's one is a well-known joke (read 'joke', not prank), or at least well known to me.
I highly doubt it's true, don't be too quick to get offended.

Run up to a person frantically and say "You Dropped your pocket!"

In a Parking lot(with someone you know) run up to their car frantically and yell "Your wheels are turning!"

At the Threshold/doorway of any room where there is a crowd going and and instantly stop and say "Crap my contact fell out!" Drop to the ground and frantically search the floor telling people to wait and not step there. After a few minutes of looking and getting people to help you stand up and say "You know what? I don't even wear contacts....." and walk off.


In all of these situations prepare for people to look at you crazy(you may receive a bird or two) but they will see the hilarity in it. :-)

What I say?

WFP wins, but that's beyond prank.

From my college days. My buddies and I were making a road trip to see some friends over at Purdue university, road tripping from Muncie IN, and I was driving. My only rules of co-pilot are 1. you do not fall asleep (this is the most important rule) and 2. you do not touch my radio. So my buddy was in the co-pilot seat and was messing with the radio for the first like 2 hours of the drive. Well after a while I notice he has stopped talking and messing with my radio so I look over and see he is passed out drooling on the inside of my car. I had 3 other folks in the back seat asleep so I told them my plan. I pulled over on the side of the road and pulled up to a Light post next to a gas station. I told them that on the count of 3 we were all going to start screaming as loud as we can. 1. 2. 3. AHHHHHHHHHHHHHHHHHHHH!!!!!!!! haha buddy woke up and about cried cause all he saw was a light pole and heard us screaming..... Needless to say he NEVER fell asleep in co-pilot seat with me again haha.
