On a sunny Saturday at the Santa Monica Pier, celebrities and their families joined host Courteney Cox at the CelEBration on the Pier to Benefit the EB Medical Research Foundation for a day of carnival rides and games. Courteney and husband David Arquette’s involvement in the organization began when her manager’s nephew contracted the rare skin disease known as Epidermolysis Bullosa.

“He’s a wonderful kid name Brandon and I saw him and it broke my heart, and I thought if I could do to anything to help I would,” Courteney, 43, tells OK! “They started this foundation and I’m a part of it, and since then, it’s really taken off. We’ve raised a lot of money and there are major strides that have happened, and hopefully, next month we’ll get an FDA approval of a first clinical trial.”

It was a fun day at the pier and David even hopped in the dunk tank to help raise money. “He’s going to get dunked real bad,” David’s sister, Patricia Arquette, tells OK!.

Keeping true to her word, she went over to the tank with her daughter, Harlow, 4, and pushed the target without attempting to throw the ball at it. “Charity work does not mean it’s not going to be fun.” In all seriousness, Patricia, 39, says, “[David and Courteney] have been really active and I’m very proud of them for doing that.”

For the couple, who have a 3-year-old daughter, Coco, the time in Santa Monica was a typical day with the family for them. “We actually come to the [Santa Monica] Pier a lot and have kids over to swim,” the former Friends star tells OK!.

“We like to get together with friends that have kids,” David, 36, adds.

Other celebrities who came out to support the cause include Adam Sandler, Joely Fisher, Noah Wyle, David Spade, Kate Beckinsale, Camryn Manheim, Holly Robinson Peete, James Marsden, Jeanne Tripplehorn and Kaley Cuoco.
