The four, crude boys from South Park, Colorado have been a part of your life for nearly 20 years. To mark the upcoming 20th season of Comedy Central’s animated sitcom, The Paley Center for Media stages a panel discussion with creators Trey Parker and Matt Stone, moderated by Viacom Music & Entertainment Group president Doug Herzog. As part of the milestone celebration, the museum also hosts South Park 20 Experience (through Sept. 25), an exhibit of 2-D/3-D models recreating 20 of the show’s most memorable moments (as chosen by fans on social media), which attendees can pose in and with. Additionally, the exhibit includes a collection of 20 show-inspired art works curated by Ron English, as well as original animation cells from the pilot episode and screenings of select episodes from the past 19 seasons.
