De Advokaat en De Barbier, of Hoe Men Pro Deo Wordt Geschoren

De Advokaat en De Barbier, of Hoe Men Pro Deo Wordt Geschoren ("The lawyer and the barber, or how men are shaven pro deo") is the title of a Dutch comedy, with songs, by C.E. Boniface.

Occasionally Boniface published an advert in the South African Chronicle or De Zuid-Afrikaan announcing a number of titles for poems, prose works, and plays he intended publishing. This is one announced in 1837.

While these titles may simply have been meant as satirical commentary, F.C.L. Bosman argues that the texts may actually have been written, or Boniface fully intended to write them, but that they were never published and/or performed. Bosman himself could find no trace of a text for this work.
