I've got a story regarding meatspin. I used to work at a computer store and my boss used to bring all of his relatives computers in for us to fix for free. My boss knew nothing about how to fix computers. Anyway, one day we thought it'd be fun to set meatspin as his brother's homepage. But, we decided to be tricky about it and add it as a second tab so he wouldn't notice it immediately. A couple weeks later my boss asked me if we had heard of a virus that plays the "You spin me right round baby" song. Of course I hadn't but I told him I'd look into it. A couple weeks we hadn't heard anything else of it so we did the same thing to his computer. He was using Internet explorer 6 most of the time. He had firefox installed by wasn't using it that much. Unfortunately I left before I ever heard anything else about it.
We did lots of fun things to him though. One time we wired usb extension cables and plugged a keyboard into his computer all the the way through the store into our tech area. We'd randomly type things and alt+tab, etc. He never found that either. Oh the good old times.
