We featured another stink-breath detector on Geekologie a while ago, but that one didn't have a back-lit screen or breathalyzer, so it sucked. But the Etiquiette Checker ($59) does, so while it still sucks, at least it's the lesser of two suckages. You just blow into the device, and it gives you a score from 1-6, 1 being go French kiss the hottest chick you can find, 6 being you may have just licked a dog's ass. But this marvel doesn't end there, no sir. It also gives you a blood alcohol reading in 0.05 increments (kind of useless). Remember the first time one of your friends got a breathalyzer and you all went out to see who could blow the highest? I do, it was great. I thought for sure I was going to win with a 0.27, but my buddy Shitty Bill ended up blowing us all out of the liquor with a 0.38.
UPDATE: Glad this guy wasn't there.
