Have mercy? Not if you’re John Stamos. Not today:

Whoa. This sounds serious. What happened?

Here’s the lowdown on the meltdown:

Video of John Stamos‘s alleged tantrum at the Netflix offices in Los Angeles was leaked Friday morning.

In the video obtained by PEOPLE and uploaded onto YouTube, Stamos is seen yelling at a receptionist.

According to a source, the incident occurred after Stamos, 52, was told an upcoming documentary series based on his life was an April Fool’s joke.

Here’s Netflix’s tweet about the documentary:

But unlike Mr. Stamos, the leaked video isn’t pretty:

Dude.

Wait a sec … what day is it, again?

A joke? Unpossible!

Ha!
