They Live! 

While They Live! wasn’t a box office success, it did become a cult classic, especially among wrestling fans. Part of that was likely due to this off-script moment.  

In this scene, Roddy Piper, playing Nada, walks into a bank to kill aliens. He said, “I have come here to chew bubblegum and kick a** … and I’m all out of bubblegum.” He claims to not know what he was going for, that it just happened. The line became a classic that people still use today.
