We've all been there.  I won a Unix "most egregious use of Unix tools" award from Usenix for this small script

   trap 'ls | wc' 1 2 3 15

   echo Reflex test. Type control-c

   ls | wc

   rm *

Because I also did "rm * .o"

I still have the ugly little warthog, anatomically correct, on my desk.
