I wouldn't recommend jamming a memory stick into your computer unless it is a usb memory stick.
The Segon RAM Card USB Flash Drive ($12 to $20 USD) is a look-a-like ram stick. It does look strange sticking out of the side of your laptop or netbook.
The next time you want to drive your tech support people crazy, just stick one of these into your system and call them up to fix the pc. They will go insane for a moment until they realize what is going on. Sounds good to me.
