Quite the interesting thread, I must say.
Let's see...I'd probably go with Sousuke Sagara of Full Metal Panic!. Even if I am completely drunk and it's terribly obvious, one could still probably convince him that it's just mouth to mouth to save my life. Silly Sagara, he'd believe anything.
Plus, it'd make for an interesting bar tale when I make it back to the tavern for more drinks.
