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".

*** 'fistbump' emotes? Are you shitting me? You have become everything you ridiculed in the past.Every time you reach out your hand to your webcam and lower your voice there is a strong cringe feeling overflowing me like a zoo lock overflows the board. I really didn't care for all the hate you got before for streaming HS all the time since I quite enjoy the game myself. But this retarded crap is too much for me to bare. Goodbye Octavian we had a good run, will keep checking the sub to see if you repented from your sellout ways and returned to the true Kripp self. See you.
