What's the fastest way to get a divorce?

Here’s what happened, I was driving my kids, Alex, Geddy, and Neil to school this morning when the song “Limelight” by Rush started to play on the radio. Everything was going smoothly at first. Then the unthinkable happened. My wife reached over and changed the channel. I was absolutely shocked. How could someone not like Rush? All I know is that I need to get a divorce NOW! What’s the fastest way to do it? I don’t care if I lose half my stuff or whatever, (except my sighed poster of Neil Peart) I just have to get away from this woman as soon as possible! Please help me!
