Actor Paul Rudd attends the "Ghostbusters: Afterlife" New York Premiere at AMC Lincoln Square Theater on November 15, 2021 in New York City.

An unusual fan theory went viral after suggesting a pretty gross method for how Paul Rudd’s Ant-Man could easily have dispensed with Josh Brolin’s Thanos in 2019’s Avengers: Endgame.

That method would involve Ant-Man shrinking himself down to crawl up Thanos’ butt and then transforming into Giant-Man, which Rudd responded to in a 2018 interview. When asked for verification if the method would work, Rudd said at the time, “I don’t know. I don’t know! I almost think it’s a question for Thanos because if there’s one thing we learned from Infinity War, it’s that Thanos could take a lot of punishment.”

“It’s an interesting tweet. I don’t think that even made it to any of the drafts.”

According to a new video, Rudd’s Ant-Man addresses the butt theory as part of the Avengers: Quantum Encounter interactive film for the Disney Wish cruise that launches this month. While standing next to Evangeline Lilly’s Wasp in the feature, Ant-Man addressed the fan theory right out of the gate.

“Look, before we start, let me address the elephant in the room,” Ant-Man says. “I’ve heard a lot of chatter out there asking why I didn’t shrink down, go in and uh [makes exploding motion with hands] kill Thanos in a really creative way. First of all, gross. Secondly, it’s much more complicated than that. Allow me to explain–”

Wasp then interjects, “If only we had the time!”
