When I was a teenager, a bunch of my friends online were tossing that around. I found a trojan and started sending it around as cupholder.exe but making it look like I wasn't the one who sent it... and just immediately logged in and opened their CD tray. Then started fucking with their system in silly ways.

Ahh the good old days when even malware wasn't that bad. Or maybe I was just a really stupid kid. At least I password-locked the trojan and removed it when I left.
