Interesting Hobbies of the 21st Century.

I am sicker than I thought. I just hope Blair doesn't introduce random, home visits by state-appointed psychiatrists or I'm done for.
I discovered the above during a clearout of the garage - two bags, filled to bursting with corks. Yes, bloody corks!! I had forgotten they were there but I do remember deciding to start collecting them. I know, I know. The word which springs immediately to mind is "WHY?". I'm damned if I know, is the honest answer.
I have some vague recollection of wanting to make something for my pond in the garden, cork being of a floaty nature and all, but quite what escapes me. Then I looked at the wider picture. A middle-aged man whose hobby is collecting corks - Jesus, that won't look good on the committal form!
It is, of course, typical of me. I have to confess that I am somewhat "anal". The kaftan and scented candle brigade who are into astrology would say it was because my starsign is Virgo and I am typical of the breed. I actually share my birthday with Hugh Grant (same year as well) and Arthur Mullard. Sadly, I think I am more akin to Arthur than Hugh.
The more perceptive readers will have realised that my odd collection says more about my drinking habits than it does about my unbalanced mind. That is true but, cork collecting aside, a man has to have a hobby.
Anyway, in an effort to cleanse myself of my silly habits at the start of this new year, I have a pointless hobby and about 200 corks to send to Grantham - unless anyone has any other ideas about what I can do with them (I have a feeling I'm going to regret asking that question)?
