Like all real Berliners Sebastian Lehmann actually comes from Southern Germany. That's why he often talks on the phone with his parents in the province of Baden. They talk about his breadless art as a so-called writer, the consistency of gummy bears, frozen pizza as a main meal and why there are still no grandchildren on the way. Sebastian took down the phone calls and now reads them out on stage and on the radio. His mother is proud, his father wouldn't comment and hopefully hasn't changed his will.
