Mr Minko, sir! You have been bought. As I always do, you are granted a means of escape should you not wish to be owned by a vagrant mathematician. (I just caution you to keep the tail down after you light the fuse. It can torch a tookas something fierce.) You, of course, need to choose and animal and a habitat, but there is time for that. Welcome to the dark side....okay, so not dark, but maybe not so well lit side. Robert
