The Bill Nye vs. Ken Ham Debate.
I use the term "debate" lightly, as one of the participants (Nye) actually used evidence and reason to make his points, whereas the creationist simply used appeals to authority and ignorance.
Nye did quite well, in my opinion. I think that he could have rebutted Ham's critique of radioisotope dating a bit more forcefully and that he could have called him out a bit more one the obvious contradictions he talked himself into, but overall Bill did a great job. He was well spoken in conveying his message, while avoiding offending those Christians who may have been on the fence over the issue.
I originally thought this debate was a bad idea and I am glad to say that Bill Nye proved me wrong in that regard. It is a shame that the Ken Ham will make money off of this in videos and free publicity, however.
