Ah yessss... There are many places where syntactic near-misses are still valid
commands. Like the time I wanted to copy a couple of files from a friend's
directory to mine. Using C-Shell, my command was intended to be

	     cp friend/{a,b} .

but my finger slipped and missed the "." so what I actually typed was
expanded to

	     cp friend/a friend/b

and my friend's "b" file was replaced by his "a" file. Luckily, it wasn't too
hard to reconstruct "b", but it did encourage him to reset his umask to 002
so others couldn't write to his files.

My "favourite" in this line is in vi (or other unix editor):

:!rm tmp
:!ll *.c

If when typing the above sequence you see the following message:

	tmpll: not found

you know you have just wiped out your source.  I am so used to
repeating commands with !! that I sometimes double the !
accidentally.  (ll is an alias or shell script for ls -l.)
