All the action happens off-screen, but reportedly it was the judge throwing punches. His conduct on (and off) the bench is terrible, but it also seems like it was a bad idea for the public defender to apparently take him up on his challenge by storming back there in response to a judicial taunt.
According to this report, it's the judge the audience is applauding at the end of the clip, but neither one deserves anything but shocked silence.
Update: Later reports said that both combatants would be taking some time off while the Florida Bar and (probably) the Judicial Qualifications Commission look into the matter. One report quoted another local attorney who knows both the fighters as saying the incident surprised him, and he wondered if it had resulted from "a misunderstood prank by the judge." You never know. Maybe they are both in a local Shakespeare company and suddenly realized they needed to rehearse a scene from Macbeth. Let's not rush to judgment.
My posts contain some additional background material on the case (not that you need much), as well as some clarification from the lawyer who was asking the questions. But the idea of doing a video recreation is absolute genius, and laugh-out-loud funny.
I'm sure the actors are exaggerating the demeanor of those involved somewhat, although there's apparently no video of the actual deposition, so who knows? But they may not be exaggerating that much.
You might turn the volume down or close your office door, because there is some yelling.
The parliament was Italy's, and the fish was reportedly a sea bass:
If you want to know why he was waving it, here'sthe story, but I really think this is one where the waving of the fish (which starts at :29) is more important than why it was waved.
The lawmaker was ejected from the chamber after he refused to stop waving the sea bass, although it seems to me he should have a right to do that if he wants to. Nobody complained when someone brought a penguin to the Kentucky Senate, at least not until it pooped on the floor.
