Circa 1998 I was a teenage Linux zealot who would attend LAN parties carrying a Linux box. It actually worked -- at the time, WINE practically existed to support Starcraft, Quake 2 could run natively, and that covered like 95% of what people were playing.

One time I thought it would be funny to run a shell script that looped through every Windows share on the network and tried to open `CON/CON` on it, resulting in a prompt Blue Screen of Death for each machine.

For some reason my friends did not think it was funny.
