At CSRI, I learned that there was a program called f**k[1].c.

I looked at the source code.

It contained all sorts of harmful actions that would, literally, break physical devices (such as printers, etc.).

All of the code was carefully commented out.

End of Session

After some playing around, I typed

> f**k me.

My session ended abruptly.

[1] That word was very verbotten at the time.
