Here's an entertaining exercise.  (I suggest you do it in a scratch
directory that you can delete by a "rm -rf" if all else fails.)

Create a file "-f" by doing an "echo > -f".  Adding a few more files
to this directory will make life a bit more fun.  Now try to do anything
useful with the "-f" file (ls, rm, cat, ...).  I won't spoil the fun
by revealing what's going on here.
