Today may be April Fool's Day, but Wieden & Kennedy is celebrating a different date -- that of its Founder's Day. The agency was born 33 years ago, and so has revamped its website, wk.com, to reflect its history. On the site you can see 33 pieces of creative from the '80s and early '90s, including work for Nike, Speedo, Memorex and Honda. Among the gems are the famous "Bo Knows" commercial, a 1993 spot for YM Magazine directed by a budding David Fincher and featuring a young Angelina Jolie and a claymation Nike ad written by up-and-coming copywriter Dan Wieden and art director David Kennedy. You can also watch an early promo video featuring the young duo, as well as today's president Dave Luhr and global executive creative director Susan Hoffman.
