C:\con\con 

A bug on old Windows computers that coincidentally, when typed into the run dialog box, and then running, would blue screen the computer. It was never patched. Pretty normal for an old Windows OS, but it's a good way to prank your friends.

C:\con\con can often be used as a prank like this:

Suki: So, you type C comma backward slash con backward slash (C:\con]con) and then hit enter, alright?
Hikaru: Yes, what happens when I hit enter?
Suki: Something happens!
*Hikaru hits Enter.
*The computer bluescreens, causing Suki to laugh.
