This guy (and about 50% of the time hos partner Val, too) somehow gets all his interviewees to relax and just talk, have a laugh, and by doing that gets them to offer up some of their thoughts on .. life. Like, deep stuff, stuff that has meaning for them beyongld their public personas.
OK, you could say that that works because it's comedians talking to comedians (and I'll admit I have never heard Bo Burnham talk that freely anywhere else) but what about Chris Martin, Malcolm Gladwell? I think Pete + Val are just so genuinely well-intentioned and always looking for the best in people, that his guests just know it's safe to talk. I've heard some great, thought-provoking stuff here, and some tea-splurting funnies .. not usually from the people I expected it from, either.
