In the newest clip for the upcoming Grateful Dead documentary Long Strange Trip Senator Al Franken is featured as he talks about experiencing the Grateful Dead culture as a young person.

“I’m a very gentle person,” Franken says of some of the more aggressive characters in the Dead’s scene. “So that aspect of it—just frightened me.”

He also recounts marveling over Deadheads going into the bathroom barefoot. “I can’t handle that,” Franken joked.
