It’s hard to imagine, but Ken Jeong is capable of getting serious when the time calls. The Hangover Part II star is a supporter of Stand Up To Cancer, an initiative geared towards accelerating cancer research with the help of the entertainment industry. The organization is fueled by the star power of The Jonas Brothers, Scarlett Johansson, Emma Stone and so many more.

Just as The Hangover Part II is about to hit theaters, Stand Up To Cancer released a brand new video featuring Jeong behind-the-scenes at their 2010 SU2C live show. While Jeong certainly enjoys some of his usual goofy humor, he cleverly ties in the art of stripping down on set to doing so in the doctor’s office as his wife is a breast cancer survivor.

As you’ve still got a few days until The Hangover Part II arrives, use the time to check out Jeong’s Stand Up To Cancer video as well as the organization’s website where you can learn how to get involved yourself.
