STOP! You are too drunk to make that phone call

So apparently there are phones in South Korea that have a breathalyzer on it. And when you get too drunk it prevents you from dialing certain people in your phone book. Now, I don't really have a drunk dialing problem, but I certainly know of others that do. The phone will be making an appearance here in the U.S. in the not to distant future. Just think, you're at the bar, you think its a great idea to call that ex of yours for a booty call or what not but instead you get a display: "You are too drunk to make that phone call." It'd be even better if it call you out in a loud tone, sort of like the metro farecard machine when your card gets declined. (From ABC News and Sumanesq)
