If you're ever asked to define irony and need an example, this would be a great one! It's so crazy, it must be true. A device installed to prevent a black out at the Super Bowl is what actually caused it! Entergy in New Orleans said the relay located in what the call 'the vault' is to blame. I don't understand any of that, but I'm betting someone has egg on their face and I'm glad that it's not Beyonce!
