Brings to mind... CoK virus (Cat on Keyboard)...
I had a script open on my box, way back, probably basic or pascal... saved it, and went upstairs to eat lunch...
Came back down after lunch, went to build the exe (or maybe .com at the time), and suddenly the compiler started throwing mad errors... I am pretty good with an in-line script... maybe one error or two... but this was crazy.
So I opened the script to see wtf... I swear, the cat got on the kb, opened that file, typed in a hot buttload of gobbledygook (along with two lines that actually worked)... twenty or so lines in three places in the code... saved it, and walked off....
