I believe that on our system `K/D' would at least ask whether you really
wanted to delete everything; this warning could be suppressed by doubling the
switch: `K/D/D'.  `K/K' was also some sort of delete-and-logout, although not
quite as bad.  Typing just `K' would prompt for the missing switch, using the
prompt `Confirm:'.  Unfortunately some people thought that answering `K' again
was the proper way to confirm this.

Ichabod (not his real name) wrote an interesting program called `Twenty
Questions', which would ask a series of multiple-choice questions, and prompt
with `.' for the answer.  Some questions were compound, and expected the
answers separated by `/'.  After asking the twentieth question, the program
would exit instead of prompt (you can't tell the difference, since the system
prompt is also `.').  The answer to the question, of course, was `K/D/D'.
