We're getting closer and closer to finally seeing Avengers: Endgame in theaters, and while there's a shit-ton of theories about how our fave superhero squad saves the day from the villainous Thanos, the theory that...intrigues the Marvel fandom the most is definitely the one where Ant-Man (played by the never-aging Paul Rudd) defeats him by shrinking down and crawling up his butthole. 

During a recent appearance on the BBC's The Graham Norton Show this past weekend, host Graham Norton asked Paul (who was sitting next to his fine AF Avengers: Endgame co-star Chris Hemsworth) to elaborate more on the bum-tastic Thanos fan theory...

"A lot of people have asked me if I shrink down and go into Thanos in a certain orifice and then grow giant-sized," Paul jokingly explained. 

"That would do it!" Norton replied.

"Why not the ear or the nose??" Paul continued. "Why does it have to be...?" 

Watch Paul give us his thoughts on Ant-Man crawling up Thanos' butthole in the video below! 

And catch Avengers: Endgame when it hits theaters on April 26!
