'Avengers: Endgame' cast explain how bathroom breaks should work during the movie

Three hours is a long time to sit in one seat without going to the bathroom -- even if you do have the latest Avengers movie to distract you.

Well, good news -- the cast of Endgame has some tips on how to get around this particular issue.

"Well, Mark said that you should wear a diaper," says Scarlett Johansson in the Jimmy Kimmel Live! clip above. "Then you don't have to get up. But you're also sitting in your own urine..."

Paul Rudd, meanwhile, has a slightly different -- albeit equally gross -- suggestion.

"Well, not having seen the film, I would say get one of those giant tubs of popcorn, and then just like lower it under the seat in the middle of the movie," he says.

All solid advice.
