Dr. Venegas is the official internist of the Russ Martin Show. He provides medical care and treatment to all members of the show, except for Trey. Seems the two of them had a falling out in the Summer of 2006 and no longer speak to each other.
Carlos has been known to put his pictures up on MySpace, which gives Russ a chance to use the Chicken sounder in the background while talking to him. Sometimes, Carlos' advice isn't what Russ wants to hear; at which times a duck mysteriously appears in the background of the conversations.
Carlos was also a member of the Russ Martin Show Band for a time. However, his desire not to wear white pants, and his inability to practice without getting upset led to his removal from the band.
