Throughout The Rehearsal Season 2 -- and really, throughout the entirety of his career -- Nathan Fielder has proven time and again that he always has another trick up his sleeve. So it really shouldn't come as a surprise that Sunday night's finale of his hit HBO series features what is perhaps his longest and most involved comedy con to date. And yet, it's still pretty difficult to believe he managed to pull this one off.

After spending the first five episodes of Season 2 building an argument in support of his thesis that many plane crashes are caused by co-pilots facing difficulty speaking up to their captains when they think something is amiss, the finale flashed back two years earlier to show how Fielder spent months obtaining his commercial pilot license in order to be able to captain a real Boeing 737 plane with real passengers onboard at risk of all the real dangers of flying. However, he first had to learn how to do said flying, which he soon discovered required a skillset that didn't come easily to him.

"When I first began this project, I decided there was no better way to understand pilots than by becoming one myself," he explained in a voiceover accompanying clips of himself taking flying lessons. "But it became clear very quickly that I was not a natural at this, especially when it came to landing the plane."
