I really miss Calvin and Hobbes. Bill Watterson gave us something really special. I have recently passed all my old books down to my daughter, so her generation can enjoy them too.
My daughter had one of those kiddie doctor sets when she was younger. I was amazed to find that the simple stethoscope it had did indeed work- and worked quite well. I'm sure not as good as a doctors stethoscope though.
I think some of you have been watching too many super hero special effects movies.
