Hollywood actor Dennis Quaid is gearing up to be the next viral Internet star after a video of him freaking out on set has hit the interwebs.

Apparently a bystander walked onto the set of Quaid's new movie, 'The Art of More,' and talked to another worker. And that's when Quaid completely loses it.

“I am acting here, and this [expletive] wanders onto my set. I can’t even get a line out until Dopey the [expletive] starts whispering in your ear, and you’re not even watching anymore!" Quaid screams.

Watch for yourself, and be warned: there's a lot of language in the video.

But as it turns out ... 

The whole thing was completely fake. While a lot of folks were pointing fingers at Jimmy Kimmel because of his history of pulling such pranks, the folks at Funny or Die were the ones responsible.

It's actually a pretty good thing Dennis really doesn't act like that. He always seemed like a nice guy.
