“It’s burning my face, and I mean burning.”

And I’m like, ‘I don’t know what this green fluid is.'”

So, naturally, what did he do?

“I’m rubbing my face and, suddenly, it’s in my throat.

It’s in my mouth.

It’s up my nose.

It’s in my eyes,” Butler told hostSeth Meyers.

“It’s burning my face, and I meanburning.”

“It turns out this is essentially phosphoric acid,” he continued.

“And the airline pilots that were there watching go, ‘No!'”

Meanwhile, Butler said, “I’m just, like, burning alive…

So it was intense.

It actually burned for hours, but it was great for the sequence.”

Watch Butler discuss feeling the burn and casually saving the lives of multiple people in the clip above.
