At its best the humour has a cathartic quality that eases our fears about the things that make us squeamish - but the routine is constantly in danger of slipping into "too much information" territory.
Bishop seems well aware of the hazard and displays a cheerful curiosity about how audiences accept some outrageously risqué jokes but suddenly become uncomfortable when an invisible line is crossed.
The show climaxes with some very sharp observations about NZ politics in which Paula Bennett's offer of free contraception for beneficiaries becomes the subject of a wickedly clever rap.
