MATLAB

Do you have access to MATLAB? Try typing
>>why
at the command prompt. Try it several times.

Now try
>>why(x)
where x is some number. Try various numbers.

Now try this:
>>for x = 1:1000
why(x)
end


The best part? There is a help file for this command.
>>help why
WHY Provides succinct answers to almost any question.
WHY, by itself, provides a random answer.
WHY(N) provides the N-th answer.
Please embellish or modify this function to suit your own tastes.
