Hooligans foiled again

No way man, every time a good soccer crowd gets together there must be chanting and general singing. But now 'scientists' (although I hesitate to call them that) have found that playing crowd noisees back with a delay stops hooligan's singing. Those hooligans never know what hit them and they stumble around in a confused manner without the ability to sing in tune. This is such a waste of an invention that I can't believe it. Remember there are only a limited number of inventions in the world and the more crap ones there are the less cures for cancer we get.
