How do you keep yourself from drunk dialing?

So I had a bunch of lovely friends over this weekend, and somehow the conversation turned toward drunk dialing. You know how it can be: You just broke up with someone you're convinced you may or may not be still in love with, you've had a couple cocktails, it seems like a great idea for you to contact said person and express your undying love for them and possibly convince them that you never should've parted in the first place. Yet it never fails that the next day you live to regret the drunk dial, right?

People have resorted to the craziest things to prevent this from occurring in the first place. One person put her phone in the freezer, (possibly the worst idea since well, drunk dialing). Others remove their battery and while this is effective, becomes a bummer when it's M.I.A. the next day. The cumulative question here is, what is the best way to prevent the party foul that is drunk dialing? Anyone? And have you ever had a drunk dial that resulted in anything less than, "Oh man, what was I thinking?"
