How to annoy kmart staff by doing something to the display computers
So one day i was in Kmart with some mates, very bored,and i saw that Kmart had a laptop on display.
It was horrible, 512mb ram and Vista Basic. It disgusted me. So i decided to do something to it that would annoy the living sh#t out of the staff.

What i did was opened notepad and typed in
msgbox ("#%!@ YOU CUSTOMER, DONT BUY ME!")
Then copyed and pasted it till it was on the page about 10000 times
After that saved it in the startup folder as a .vbs file.
I resterted the laptop and walked off.

About 15 minutes later i went back and found 4 Kmart staff gathered around the laptop, one of them just kept on pressing ok but the message box just kept on popping up, it was hilarious cause they didnt know what to do.

3 Weeks later when we went there again, the vbs file was still there, so just to annoy the staff a bit more i created multiple shortcuts to every program on the computer and placed them in the startup folder. From that day on i havent been to kmart since
