this man received a sudoku puzzle to solve for his sudoku youtube channel. he was told he wasn't allowed to look at it until he was recording. so on the video, he opened it up and immediately said "i'm being made fun of. this obviously isn't solvable. he's about to get an angry phone call"
..."well, i can place a few digits here and here. but that's it. after that it's impossible."
"well i suppose i could narrow down this digit here but like. this grid does not have a unique solution. it can't."
