Before Monday’s opening debate between the Democratic and Republican candidates in this year’s US presidential election, Hillary Clinton has faced off in her most gruelling TV interview to date, taking part in Zach Galifianakis’s infamously wicked comic short Between Two Ferns.

Taking the chair previously occupied by the likes of President Barack Obama, pop star Justin Bieber, and actor Jon Hamm, Galifianakis poses several excruciating questions at the former Secretary of State and First Lady.

“I really regret doing this,” says the stony-faced politician at one point. Between Two Ferns is just the latest in Clinton’s appearances with famous America comics, having previously cameoed in episodes of Broad City, The Tonight Show and Saturday Night Live.
