Good Pranks

[Elro]

Anyone have any good ideas for a prank? April Fool's Day is coming up, and I for one plan to do something.

I guess I'll start off with a couple I have found:

Ketchup Packets under Toilet Seat: Put two packets under the lip of the toilet seat (you know, towards the front edge. On open seats, you can put one under each half). Poke a hole in the top of each top packet and in the bottom of each bottom packet. Then go away cackling like a maniac.
Result: Someone may become very startled to find a red substance in the water and on his/her rear end.
Risk Factor: Probably small, if it's a public bathroom.

(I actually have 65 ketchup packets - 1.3 ketchup bottles - saved up and this unfortunately is the only prank I could find involving them. If anyone knows any others involving ketchup packets, please let me know!)

Fake Broken Window: Get a bag of broken glass. If someone leaves his or her car door open, roll down the window all the way so it isn't visible. Pour broken glass onto closest seat. Run away cackling like a maniac.
Result: When the victim returns to the car, he or she will experience some form of anger due to thinking a window was broken out.
Risk Factor: Higher if the victim is not far away, or if you know the victim.

Come on, there's plenty of pranks out there. Got any favorites?

If you know someone with a pet, cut off the pet's head late at night and put it in their bed. That'll get em!

April Fool's Day jokes have never worked on me. I always realize what day it is and trust no one. :ph34r:

I never really trust anyone to begin with. :/
I would think that one of the best tricks would be to start off the day by smirking at your "victim", without really intending to do anything. Then the victim will spend the entire day wary of your actions. But then the victim may nag all day about "why you made that weird face come on tell me tell me" and then it would get irritating..
Bah April Fool's Day sucks. Unless of course, it turns out that Bush didn't really win the election. And the tsunami never happened. And 9/11 was a stunt. O boy :ph34r:

(sorry I have no good april fools gags :()

*edit: I got it! Develop a set of "evidence" showing that any of the last three things indeed didn't happen and convince someone! Then the person will go around telling people and get ostracized by society. Then you can go up to the person and say "April Fools! You have no friends." And then the person will ask "Why did you tell me those things?" and you can say "because I don't like you. No that wasn't a joke. Now go away you stupid ugly thing."

wow ur ahead Elro...i havent even thought about valentine yet. but by the way, i figured out that April Fools is a good day to ask someone out. if they accept, great.(and hope they aren't playing april fools on you) if not, just say "april fools!" and be spared of the embarrassment.

and some good pranks my friend did:

1. tape with invisible tape the little flap thing under the phone receiver. wait till somebody is near the phone, and then call it. the person will pick up the phone but it will keep ringing.

2. get an Oreo, replace the cream with toothpaste.
