After earning distinction this week as the lowest-rated network broadcast in its time slot, NBC has pulled the plug on the sitcom “Animal Practice.”  This over-hyped and ill-conceived flop featured Crystal the fear-grinning capuchin monkey in a starring role. While we'd like to imagine that the cancellation was in response to the outcry of animal welfare groups and primatologists concerned about Crystal's cruel exploitation, the sad truth is that television programming is driven by advertising $$$, and this was an economic decision. Nevertheless, please consider writing to NBC Entertainment Chair Bob Greenblatt at and ask NBC to discontinue the barbaric and outdated practice of using wild animals in their future programming.
