 Like some other columnists, Royko created fictitious personae with whom he could "converse", the most famous being Slats Grobnik, a comically stereotyped working class Polish-Chicagoan.Generally, the Slats Grobnik columns described two men discussing a current event in a Polish neighborhood bar.In 1973, Royko collected several of the Grobnik columns in a collection titled "Slats Grobnik and Other Friends".
