Why Not?

Go to the Matlab command line and type 'why'. Then do it several more times. (For bonus points, find a clever way to use this command as part of a loop or some other series of commands.) I wonder how long this Easter Egg has existed? I only just found out about it today. Maybe I'm easily amused, but (a) I think this is awesome and (b) there must be some clever thing that one can do with this. :)
