Just for the record, I noticed that the iTunes description for this episode refers to Karl with K. Carl with a C is the technician from Newbridge Audio who worked on Tom's soundboard and chatted with Sanjaya on 9/8/2009. The following week his twin brother, Karl, called the show. He revealed that their parents are Carl and Kharl (it's Swiss).
The WFMU archive page also incorrectly refers to "Karl" in the 9/8/2009 show description. Sick stuff!
"Andy Warhol. Surprisingly strong running back." - Karl, 9/15/2009
