I was reading a verrryyy old issue of a mad magazine and it was about inventions. Yeah, that's right. This is probably the one of the harder threads to think of something to say in, but hey, i kindof want to see if people can think of a bunch of things...also i hope sum1 doesnt really make the invention you said and go an make a patent for it (wouldent that make you happy).

1) Name your invention (it can be one that is already invented).
2) Briefly describe how it would work. (Preferably something that is reasnably possilbe)
3) Then give reasons why it wont work...as in rip on it and make it funny as possible.

I cant give an example cuz i cant remember/think of any.
