Mark,
Now in reference to a Movie called Crocodile Dundee when Paul Hogan is in New York he says displaying an enormous knife after being held up with a normal knife thats what I call a knife.
Taking my theme further to the film Mad Max Mel Gibson an unknown until then starred in the series your pen would be entirely in character with the scenes used. Thats what I call a Pen for a description. I know for you babies it was 1979 when George Miller produced the movie.
Truly fascinating your pen rips strips off the moonshine talk on the site from time to time in reference to mirror finishes and perfection sought length of life of the Biro refill, clips positioning ad nausum when a guy like you can rip the covers off conventions and show us how to lighten up and gaze into the sunset and really have fun.
I defy anyone who views the two films I have quoted to come away unimpressed and why cause they take the mickey out of pretence and who hah we cloke ourselves in, mind you Mad Max is not for the faint hearted nor is Pen Turning per se.
Thanks for the oportunity to lighten up feel amused and impressed altogether a real new experience on the forum and I for one salute you.
Kind regards Peter.
I like that one alittle better.
