The title is from the detective show The Equalizer (1985). Coincidentally, Denzel Washington (Dr. Philip Chandler) would later star in the film remake of that series, The Equalizer (2014).
Dr. Chandler (Denzel Washington) organizes an anti apartheid protest at a local medical center. Washington would go on to play South African anti-apartheid activist Stephen Biko in Cry Freedom (1987).
It is mentioned that Jeff Rosenthal spent some time during his visit listening to Dr Craig's anecdotes of service at a MASH unit in Korea. This is one of several oblique implications through the series that Craig was a surgeon at the 4077th unit of M*A*S*H (1972).
