Zac Efron Is So Angry at Cancer He Decided to Flip It Off

By: Celebuzz / February 25, 2010

Zac Efron, abandoning his normally sweet demeanor and making rude hand gestures at the camera? Yes, but don’t be alarmed—it’s all for a good cause.

The former High School Musical hunk flipped out with cancer survivor Emily Hobson to promote the Stupid Cancer campaign, which connects young cancer victims with resources and support. The “Stupid Cancer” wristbands that Zac and Emily are wearing can be purchased in 10-packs for $9.99 per pack, with proceeds going to the I’m Too Young For This! Cancer Foundation.

Way to go, Zac! In terms of charitable efforts, that’s pretty flippin’ sweet.
