After numerous reports speculated that a viral video of Dennis Quaid having a full-blown meltdown was in fact a stunt for an episode of Jimmy Kimmel Live, the late-night host set the record straight, saying he had nothing to do with it.

“I watched this a bunch of times last night,” Kimmel said on his Tuesday night show. “And when I woke up, I was being blamed for it.”

Kimmel, who has a reputation for pranks, added, “You play like 50 pranks and all of a sudden people don’t trust you anymore.”

The video [caution: contains the F word] was uploaded to YouTube on April 10, shows the 61-year-old Day After Tomorrow star unleash a torrent of expletive-filled abuse onto his production crew when an assistant walks onto the 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,” he shouts, adding, “This is the most unprofessional set I’ve ever been on.”

According to the Wrap, Quaid’s reps have declined to comment on the video and the production company behind his latest movie The Truth said the tirade didn’t take place on their set.
