He’s the king of pranksters, but Jimmy Kimmel may not be behind a certain video sweeping the Web.

The late-night talk show host, 47, addressed the clip uploaded to YouTube of Dennis Quaid, 61, that caught the actor having an angry outburst on a movie set, amid fan speculation that it was a stunt for Jimmy Kimmel Live!

“When I woke up this morning, I was being blamed for it,” the comedian said during his Tuesday night episode.

“I have to say, it’s disappointing. You play, like, 50 pranks and all of a sudden people don’t trust you anymore,” he said with a laugh – although he never outright denied his involvement.

And although the reason for the Rookie star’s angry eruption remains a mystery, Kimmel provided his own theory about why Quaid was screaming at his colleagues while supposedly filming a movie.

“Did anyone ever consider that maybe Dennis was doing voice-over for a new cartoon?” Kimmel asked the audience.

He then aired a clip of the animated Daffy Duck making hand gestures with Quaid’s fiery lecture as the voice-over.

While a rep for Quaid has not yet responded to PEOPLE’s request for comment, a spokesperson for Mythology Entertainment – the production company behind his recent film project, Truthtold TheWrap that it did not take place on the set of their movie, which finished production last year.
