This is more of a practical joke.
The year was 2003, and the location was the West-Coast Mini Con in San Jose. We had about 30 or 40 guys.
Anyway, it's Friday night and we're all drinking heavily, and I get the idea that it would be funny to record the sound of taking damage (you know, pings and then things breaking off) as a MP3 file, and then feed that MP3 file into the Area VOX channel, and see what happened. I thought we'd need a few PCs and some audio cables, but then someone said it could be done in software.
So someone download and installed some software that let you feed any windows sound output into any windows sound input, and one of us killshot the other with 303s and 50s and we recorded the sounds of impending doom - it sounded like popcorn, with all those little bullets.
Then I went into the main area and looked for the biggest furball with the most friendlies, flew into the middle of it, started the sound software, pressed the VOX button and cried out "Look out! Check 6!!" and then played the MP3 into the Microphone input.
I didn't realize that there were about 20 guys behind us in the room looking over our shoulders.
Ho ho ho!
Huge laughs erupt around us as pretty much every friendly around us started weaving, dodging, and generally getting the poo scared out of them. Two augered by accident, I believe.
It all happened so fast that no one saw who was transmitting on VOX. Folks were chatting for a few minutes about all hearing the same thing at the same time, but not actually receiving any damage. Someone suggested that a joker was doing this exact trick on the VOX, but others said it wasn't possible.
We were giggling at that Minicon all night over this.
I almost shudder to think what other people reading this story will try next...
