"Jackass" star Steve-O was arrested in Hollywood on Sunday after climbing a crane to protest SeaWorld's treatment of orcas. Once he reached the top, he set off fireworks and showed off a balloon shaped like a killer whale that read "SeaWorld Sucks," according to the Associated Press .

He's made a career out of dumb and dangerous stunts, but the latest one had a good reason behind it.

Several fire trucks and other emergency vehicles arrived on the scene, which Steve-O took a video of from on top of his crane.

When he descended, he was arrested for suspicion of trespassing and other charges - and likely for taking up the time of dozens of emergency responders.

Whether or not you agree with this particular brand of protesting, SeaWorld's treatment of its orcas is certainly protest-worthy. Since the 2013 release of "Blackfish," several revelations have emerged about the park's questionable orca care, from drugging its animals to food deprivation to separating mothers and babies.

And the public isn't happy: Last week, SeaWorld reported an 84 percent drop in net income for its most recent quarter.

This isn't the first time Steve-O has gotten in trouble for his anti-SeaWorld efforts: He received a traffic citation last year for vandalizing a SeaWorld exit sign so it read "SeaWorld sucks."

"I have a pretty passionate stance against animal cruelty, as everyone knows," Steve-O told The Dodo at the time. "It's magical if I can take a wild and crazy stunt and do some good. Here I am setting out to entertain people and then I can do something to make a difference."

He has another message for fans this time - though this one's a bit more urgent. "Anyone wanna bail me out of jail?" he wrote on Facebook.
