Excerpt from The Best Show on WFMU with Tom Scharpling (Jan 5, 2010)
Patton Oswalt and Tom Scharpling discuss how Gallagher transitioned from a goofy hippy to an angry racist. The story of Gallagher's disastrous pseudo-Spanish show full of degrading stereotypes and insults is pretty hilarious/sad.
They also ponder the idea of Quentin Tarantino casting him in a movie to revive his career.
