Koreans get drunk?

Apparently, there is a phone with a breathalyzer (thanks for the research Michele). It's also a karaoke machine which seems to be a paradox. Don't you have to be drunk to do karaoke? Strangely, it's also a universal remote which guarantees you will lose it somewhere in your living room. It's also only available in Korea with no plans to bring it to the U.S. yet. Why only in Korea? Koreans don't even drink. They're too busy making our Nikes.
