A good idea from LG, a breath analyzer integrated into a phone, so before you crawl behind the wheel, you can make your phone vomit by breathing all over it, and you can be sure that:

1) the pink elephant on the passenger’s seat means that you’re drunk
2) the pink elephant on the passenger’s seat that talks to you after you have been drinking Coke Light all night means that you have to see your shrink
3) if point 1 and 2 are not applicable and your phone is making a lot of noise, it means that you quickly have to get some mints

Anyway, the phones that offer this function are the LG-SD410, LG-KP4100 and LG-LP4100.
