You'd think a little thing like an absent host might prevent "Between Two Ferns" from truckin' forward, but luckily for us, Zach Galifianakis got his twin brother, Seth (pictured at right), to hold down the fort and this week, Sean Penn seats down amid a pair of potted plants for another hardly hard-hitting interview.

Seth's a bit of a sensitive soul, far more Southern than Zach and easily excitable. Sean, however, is just about the opposite of that. Maybe somebody told him that he'd get an award if he made it through this, I don't know. At the very least, he can chalk it up to another humanitarian effort.

We've embedded this latest video below, and if you need to catch up on earlier episodes, look no further. (I vouch for the Charlize Theron, Natalie Portman and Jon Hamm ones above the rest, but they're all in good, exceedingly awkward fun.)
