This is a tough one to answer. Though I would have to say it was either the Cleansing of the Source or Mat kidnapping Tuon. ...Okay, it's got to be Matrim Bloody Cauthon. Not quite as flashy as the Clensing, but still a grand laugh from then to when Tuon names Mat her husband.
Alright, the iTunes version of the Podcast is running (even with me being two months behind on that). Hopefully there will be a fix for the minority of us Zune users who are still having difficulties in getting the Podcast on our portable devices.
