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

Hey Kripp, how's it going, Faeria Dev here

Hey Kripp, how's it going, Faeria Dev here. We noticed that your streams are interesting and entertaining. To fix this issue, we have decided to offer you money to play our very uninteresting and boring card game that is clearly a clone of Hearthstone. We look foward to future business with you and hope that you can sellout out a little bit more in the future.
