Some quotes that stuck - not necessarily verbatim: G: Guest (guy in the middle) H: Host (doesn't matter which one it was)
H: "but what about the south pole? antarctica." G: "doesn't exist. it's a huge wall. Nobody's ever been to antarctica" H: "but there's pictures"
H: "If the earth were flat, none of the navigation computers would work. gps and all that, is all based on maths including a sphere" G: "yeah, but... maybe not." H: "so, pilots and others who rely on that stuff, are doing it wrong?"
H: "so why do ships disappear behind the horizon?"
H: "okay, so what about space debris. what about things falling into out athmosphere and disintegrating. what about sattelites? they show a live ISS feed" G: "that's not real. I don't believe them. and sattelites, not ever. They've never shot anything up there." H: "But you can see sattelites with your naked eye!" G: "no you can't" H: "yes you can" G: "yeah, I'm pretty sure you can't. Sattelites are only about the size of a bus and a plane is ... like 3 busses, yet, when a plane is at 30.000 feet, it's almost not visible, so how could you see a sattelite that's a couple miles up?" H: "they're steadily moving lights"
and the best one:
G: "I'll believe that the earth is round, if you take a plane and fly OVER antarctica. show me that, and I'll believe you"
to which I say he'll probably not believe that either and call it "fake" even IF it's done because... he doesn't believe the ISS footage either. That's about it.
