Ray Romano, Jimmy Kimmel, Zach Galifianakis, Nick Kroll and Tig Notaro were among the funny folk at Waterkeeper Alliance’s second annual Keep It Clean comedy benefit.

“The world is getting to be a smaller place to live and we have to keep it liveable,” Romano said.  “All charities are important, but this one affects everyone in the world.”

The benefit was put on to raise money for the Waterkeeper Alliance, which fights to maintain clean water by patrolling major waterways and initiating legal action against entities who pollute major water sources.

The event, hosted by Kimmel, featured stand-up performances by seven comedians, including Wanda Sykes, J.B. Smoove and Gerald “Slink” Johnson. The topics covered in the performances ranged freely from water conservation to Donald Trump, from Scientology to a fictitious performance by the Indigo Girls. The evening’s performances were excellent across the board, but the strongest audience responses came during the sets of Kroll and Notaro.

Rachael Harris, known for her role in “The Hangover” and the newly-renewed “Lucifer” on Fox, was integral in the development of this event.

“I’d been going to these events for three or four years and I kept seeing all these very sad videos that they put together and I thought, ‘I know a lot of funny people,’ so I went to the PR director at Waterkeeper Alliance and I went, ‘Let’s have a stand-up show,’” Harris said. “People love to laugh, we need to laugh.”

Julia Louis-Dreyfus recorded a video that ran at the beginning of the show where she reprised her role as President Selina Meyer in HBO’s “Veep.” In the video, she talked about the importance of clean water while also setting the table for a comedy-filled evening.

The president of the Waterkeeper Alliance, Robert F. Kennedy Jr., spoke of the importance of clean water during the night, while noting that protecting the environment isn’t “for the sake of the fishes and the birds.”

“If we are going to meet our obligation as a generation, as a civilization — which is to create communities for our children and provide them with the same opportunities for dignity and prosperity and good health as the communities that our parents gave us — we’ve got to start by protecting our environmental infrastructure.”

In the lobby, a display showcased the Toyota Mirai. The new hydrogen car generates just one emission: pure water.
