Joe Rogan and Brian Callan Weightlifting Bit

"I don't know what is fun. It's like an old album or something," he said. "He has a bit about watching tigers. And Joe's really good with animal sounds." He was referring to the opening sketch for Rogan's first special, on which Callan joked that his girlfriend had told him his ass was flat. The two are seen lifting weights in the basement and getting pumped up as they do it.
