Thank you, thank you, thank you! Between Two Ferns is my favorite thing on Funny or Die and there hasn't been a new one in a long time. This is not the best one ever, but you should definitely check out the others.
I've been a huge fan of Zach Galifianakis for quite a while. I highly recommend both Zach Galifianakis: Live at the Purple Onion and The Comedians of Comedy (both should be on Netflix: Instant Watch). He performed at Sasquatch last year. I caught most of his set (had to split time with that and TV on the Radio) and it was a riot. On the drive home the next day, my friend and I were driving along I-90 and saw a bright yellow Corvette in the slow lane. Eventually we passed it and I mention to my friend it was Zach driving. He didn't believe me, so he slowed way down so Zach would pass us. Sure enough the Corvette passed (friend agrees it's Zach) so my friend sped up to pass him again and encouraged me to wave or something. As we passed him again, I gave him a thumbs up and he waved back. The moral of the story: My friend and I are idiots.
