Comedian Darrell Hammond is the longest-serving cast member in the history of Saturday Night Live and for 14 seasons was often the sketch comedy show’s go-to impressionist. Before he left SNL in 2009, Hammond honed impressions of dozens of celebrities, but he’s probably best-known for one of them: President Bill Clinton, which was an almost weekly occurrence on the show in the late 1990s thanks to the Monica Lewinsky scandal.
Hammond, who recently took on the role of Col. Sanders in a new advertising campaign for KFC, is back at SNL as the show’s announcer, and his lip-biting, thumb-wagging Clinton has returned as well. Last week, Hammond stopped by TIME’s offices and shared a few tricks on how to become the former president. (Hint: Perfect a “vocal crinkle.”)
