Three inventions -- free, for you

I offer to Blogpals 3 inventions --- at no cost.

1) A foldable tennis racket --- a good idea when traveling

2) An inflatable suitcase --- to let cab-drivers think you are going to the airport when you are just going a few blocks away and it's raining. (Not advised with surly cab-drivers.)

3) Paste-on pointed thumbs --- for use on Blackberberries. Why hasn't anyone thought of that? Must I, an authenic technophobe --- think of everything?
