This is surreal, if you run this code, the output is ... well 
interesting to say the least. Not sure how it meets the OP requirements 
but in fairness I'm not sure what the OP requirements are in the fist 
place so who's to say it's not 'correct'

Incidentally if you strip all the unnecessary garbage from the code and 
introduce some sanity to the formating it does make it slightly easier 
to read.

Very strange, is it mushroom season where you are?
