What was your best April fools gag this year?

[Radiant Memphis]

  So, what was your best prank or gag you brought about this year on all Fools day?
Mine revolved around telling most everyone I saw, as well as posting over the net that Johnny Depp was dead. Had people going for hours about it. Sometimes people can be very gullible.

I made a fake virus program for my brothers computer. 

It displayed a couple of messages that scared the living daylights out of him.

My masterful prank consisted of completely forgetting it was April the first. I was amazed when I found out the next day, as I had lost virtually no dignity from the experience.

@Jimmeh - that was cruel . You deserved it

You know, I've honestly never done an april fools prank. All of my pranks are situational last minute pranks. The ones that need tons of planning or equipment only seem to work in the movies.

well it wasn't an april fool, but ages ago I sent fake emails out to this guy using a PHP form, pretending to be some girl from his old school and told him that she fancicied him, he was so cnfused about it he went all the wya to his old school to find out if he could see who she was.

Then another time I pretended to be billgates@microsoft.com and asked him to uninstall his pirate copy of windows. He was so scare he asked the tutor about it, who had to explain to him why it was fake.

Well, it was a joke, but it wasn't successful...

We took a friend's trampoline and tried to sink it in his pool. For some reason it floated

I love the old 'Rubber band around faucet hose' trick. Gets em' every time

Air in the piping probally. I remember once when I was about 8 years old, I was at the local pool for our neighborhood. It was the last day of summer, and we had been getting crap from the lifeguards all year. You see, this was pre-pubescent hijinks at it's best, and we had no concept whatsoever of the female form. While they were only 5 years older than us, it felt much older. The man was keeping us down, and something had to be done.

So, we decided to sink the lawn chairs. Unfortuanately, they took much longer to sink than expected. We got caught after successfully sinking one. Somehow that single lawn chair represented all that was gloryful, and while we were overcome, I think we all felt like our small victory was sufficient enough.

That was the greatest summer ever... 

EDIT: Err... well my point was this: the piping in a lawn chair and trampoline are similar, and the reason why your plan failed was most likely similar to my problem. Uh, and I guess mine was a prank of sorts too.

plus the large surface area relative to its mass

i didnt really do anything to fool anyone i see it as lame unless you go way over the top, and i dont have the time to do that
