If you haven't seen any of the previous installments of "Between Two Ferns with Zach Galifianakis", I'd encourage you to hit them up here before viewing the below. The very funny web series on Will Ferrel's FunnyOrDie site features many of today's leading actors on a faux talkshow hosted by comedian Zach Galifianakis.

The series is very much an homage to some old-school skits from "Saturday Night Live" featuring a nervous (and insulting) host with little to no knowledge of this guests — and absolutely zero tact. Take this recent exchange with Sean Penn regarding this charity work in Haiti:

Galifanakis: I’m real interested in the work you’ve been doing down in Haiti. Tell us a little about that?
Penn: Well, after the…
Galifanakis: Is there a Six Flags down there?
Penn: There’s not. No.
Galifanakis: OK, we can move on.

Have a look below to see the rest of Penn in the hot seat. I'm honestly surprised he didn't get up and beat Galifianakis — ala Bradley Cooper.
