On March 8, 2014, Malaysia Airlines Flight 370—and the 239 people on board—mysteriously vanished. Plane debris wasn't found until July 2015, and investigators have yet to find the rest of the plane.

As MH370's disappearance attracted international attention, some proposed various theories about its fate, including Lemon, who questioned whether it could've been sucked into a black hole. His primary sources for these conspiracy theories? Random Twitter accounts, of course. 

Mary Schiavo, a former U.S. Department of Transportation inspector general, was quick to shut down Lemon's question:

"Well, it is ... A small black hole would suck in our entire universe so we know it's not that. The Bermuda Triangle is often weather. And Lost is a TV show. So I think—I always like things for which there's data, history, crunch the numbers. So for me, those aren't there.
