You are trapped in a room of 5 old people who barely know how to use a computer. You must survive in there for 1 hours. The catch is, that they will look at you and ask you a lot of questions about computer related things. Often times they will repeat their question moments later.
Just constantly stick your finger up your nose, scratch your balls, etc. Make them dirty, greasy,... You get it. If there are "better" means (e.g. food) available, use that. Then play dumb and try to use their computer as if it was a phone and try to do everything as if it had a touch screen. Smear it all over their screen. Cuss as the PC doesn't react, try again, get visibly angry and irritated.
They'll stop asking questions fast. Probably right after they realize what you did to the first PC.
If the socks are removed or altered your fiancé's collar will be remotely detonated. The only key is hidden in the farthest stall of this 7-Eleven bathroom. Hope you don't get... cold feet
