Here’s a clip from last night’s Late Show, where Stephen Colbert chats with Marc Maron about their old Comedy Central shows in the ‘90s, the time Maron interviewed President Obama in his garage on WTF, and his new role as a coked-up manager/director on Netflix’s new series GLOW – a role he brought plenty of real-life experience to. “I did my graduate work in cocaine in Hollywood. It was intense – it was an intense course, it was a year,†Maron says. “It all happens at once. When you’re studying cocaine, it all comes, and then eventually you’re psychotic and you have to leave and stop.â€
