Dear Olafman - I have never done anything like this before! Here is my contribution:
------------------------------------------------
There was once a Mister Zen
Who often flew on a mileage Run
Then came Corona and Spun
A web that banned all his Fun
------------------------------------------------
Now, I hope I am going to win that
Singapore Airlines First Class Lalique Pajamas
--------------------------------
standby my man - Just noticed my first line has the words "there was once".....I did not plan to copy your submission! sorry about that!
