It would be shellfish of me not to include a pun today. I once went to a fancy dress party carrying a girl on my back. When people asked what I had come as, I replied "a tortoise." and pointing to the girl I was carrying "...this is Michelle".
Sorry - feel free to groan
So today I have a shell - not sure what it's called though. It originally came from Africa when my wife was a wee lass and lived out there.
I went for the underwater type look with it.
Funny how the pattern on it makes it look out of focus.
