Hunter Parrish is just one of the many Showtime stars who are “C”ing themselves and they want you to join in.

The initiative partners Showtime’s The Big C with the American Cancer Society who want to create a world with less cancer and more birthdays.

Colbie Caillat, David Duchovny, Dave and Odette Annable, Julie Benz, Chef Gordon Ramsay, Parker Posey, and others have have joined the campaign to encourage fans to “C Yourself” with More Birthdays!

For each “C” uploaded, Showtime will donate $5 to the American Cancer Society — JJJ loves that. We definitely want more birthdays!
