I don’t even know why I post about this, but here’s the description that comes with the YouTube video. Still don’t know what to think about whether or not this is fake, but I’m starting to lean towards yes, it is fake. Or Joaquin is just really fucking crazy:

JOAQUIN PHOENIX was involved in a huge brawl while performing at a Miami night club last night, wrestling a heckler to the ground before being dragged off by security.
The actor-turned-rapper, 34, jumped off the stage mid-way through his appearance to confront the mouthy audience member.
An enraged Joaquin, sounding a little more coherent than in recent times, announced: We have a f***ing b**** in the audience.
Nodding his head while rapping to a beat, he told the man: I’ve got $1million in the bank. What have you got b****?
Joaquin who sources say arrived four hours late for the gig at the LIV night club in the Fontainebleau Miami Beach hotel then launched himself into the crowd.
The crowd chanted “beat him up, beat him up” as Joaquin got stuck in.
The incident took place at around 2am. Joaquin was in his usual get-up of suit, dirty trainers and taped-up sunglasses along with his now-trademark scruffy beard.
One fan said: I saw the guy screaming at Joaquin.
Joaquin then flipped and jumped into the crowd.
The Walk The Line star, who has battled alcohol addiction in the past, has prompted concerns for his well-being since announcing his retirement from acting in October.
He made a disastrous hip-hop debut in Las Vegas in January where he performed three tracks before falling off stage.
Joaquin then caused further worry with a shambolic appearance on David Letterman’s Late Show.
However many fans feel the whole thing is a hoax, as all the incidents have been filmed by his brother-in-law CASEY AFFLECK.
Casey was once again in the audience in Miami, capturing the the performance on his video camera.
