http://www.google.com/mobile/default/brainsearch.htmlas for me, I printscreened the screen of one of my colleagues, hide his icons and task bar and put the previously saved printscreen as background.
He started by thinking the problem came from the click of the mouse that did not work anymore, looked for another one, then tried many things for half an hour. He rebooted his computer a few times and did not understand why his main software was on the screen whenever he started the computer although the task manager said it was not started. After this half an hour, he already had deleted his main work software and was downloading it to try to install it again. So before he delete important stuff on his computer, I asked him what day today was.
And one of my friends asked me for some friends' phone numbers. One of those I gave her was the french equivalent of the flirt divert.
I'm still waiting to do some more.
