Just when you least expect it, there's a brand-new episode of "Between Two Ferns," the hit series that's not quite a talk show but is most definitely starring Zach Galifianakis — or, in this case, his "twin brother" Seth — and featuring Sean Penn. Penn says that talking about himself and being a movie star ain't all it's cracked up to be, which I'm sure comes as a shocker to Seth. Thank you, Comedy Death-Ray!
