I just had my friend going crazy... i took a screen shot of his iphone home screen then opened it in the photo album so it looked like his home screen, i kept pressing the buttons and told him dude i think you got a lemon iphone look the touch screen isnt working. now he is a total iphone newbie so when the camera roll heading popped up i just told him his phone was going crazy. needless to say he was a little pissed off after he stood in line for 3 hours lol. after i had him going for a few minutes and him threatening to take the 20 minute drive back to the apple store where he got it i finally fessed up lol
