'''Does not know "come here" from "sic' them"''' is an idiom to denote complete ignorance. The person or thing that is being discussed is being compared to a [[dog]] that does confuses the command to "come here" with the command to "sic them" (that is to attack). When spoken with a thick Texas accent, the phrase rolls of the tongue as "don't know comer from sikum." It has also been shorted to "Here from sic 'im".<ref>{{cite news|url=http://www.nytimes.com/1993/06/13/magazine/on-language-sic-em.html|title=ON LANGUAGE; Sic 'Em!|first=William
