>>21077673The sign is a subtle nigger joke. The shop is called "Sneed's Nigger Feed & Seed", where "nigger feed" and "seed" both end in the sound "-eed", thus rhyming with the name of the owner, Nigger Sneed. The sign says that the shop was "Formerly Nigger Chuck's", implying that the two nigger words beginning with "F" and "S" would have ended with "-uck", rhyming with "Nigger Chuck". So, when Nigger Chuck owned the nigger shop, it would have been called "Nigger Chuck's Nigger Feeduck and Seeduck".
