If they can't protect the Earth, you can be damn well sure they'll swear about it.

Based on the new "Age of Ultron " gag reel, it's clear the Avengers never listened to Captain America 's warning to watch their potty mouths. In the new video, which comes in anticipation of the Sept. 8 digital release, highlights include Black Widow stealing Cap's line, Bruce Banner having trouble talking about science and Nick Fury doing his best Samuel L. Jackson impression.

"Avengers: Age of Ultron" is available on Digital HD Sept. 8 and Blu-ray Oct. 2.
