Ken Jeong is always a welcome face in advertising. He did that memorable Pepto-Bismol spot set inside the human digestive tract, and he's also done PSA work like this disco-thumpin' spot for the American Heart Association. Now, the Community actor is going green in a new "The More You Know" clip as part of NBCUniversal's "Green is Universal" environmental initiative. The video below contains Jeong's new ad, co-starring shag carpeting, as well as second spot with Chuck actors Zachary Levi and Joshua Gomez. (There are also behind-the-scenes interviews with all three.) The spots will air during Green Week on Nov. 13-20. NBCUniversal's green initiative is now its fifth year. This year's theme is "Mugs Save Trees," which urges people to use reusable mugs and cups instead of disposable ones—and save 9 million trees a year. During Green Week, Green is Universal will go to agencies with a coffee bar and serve up specialty coffee drinks in reusable mugs. Free coffee will also be distributed to the public from coffee carts and coffee shops around New York, Los Angeles and Chicago. There's also a Facebook contest where people can upload their own "mugs"—photos of themselves holding their reusable mugs—to win prizes including mugs signed by NBCUniversal talent and a trip to Universal Hollywood. Also, an entire graphics package developed with Wolff Olins incorporates NBC's peacock feather shape into a variety of shapes such as a lightbulb, a leaf, and a new Green is Universal logo, which mimics a recycling symbol.
