Reasons you should be at the Double Down Saloon (4640 Paradise Road) from 6 to 9 p.m. this Thursday, Feb. 28:

1. There will be live entertainment by DJ Bozo and Szandora the Hula Hoop Chick.

2. You need Ass Juice.

3. Dirk Vermin will be there. And he said so.

4. Toni James will be there. Don’t make him cry and ruin his makeup.

5. The Las Vegas arts community is coming together for “The Funk-Raiser” to raise funds to help offset First Friday founder and Funk House owner Cindy Funkhouser’s medical bills. The art scene pioneer has been battling a rare form of cancer since last year and though she’s pulled through like the fighter she is, her medical expenses have piled up.

Funkhouser, who also co-owns The Fallout gallery with husband Rick Dominguez, is far too proud to ask for help, but her family and friends are banding together to produce this auction to create a fun way to gather some dough to ease her wallet’s strain.

The live auction, emceed by Vermin and James, will feature works donated by local artists such as Mark T. Zeilman, Dray and Tony Bondi, as well as other items such as massages, jewelry, dinners, shows and salon services.

Do you need another reason to be at the Double Down on Thursday night? We didn’t think so.
