Tic Tac Toe Turns Violent

Alright, listen up, you chucklehead. You think you're slick with your 'tic tac toe' shenanigans, huh? First of all, your sister is obviously a bit unhinged if she pulls out a knife for a simple game. This is why she should be in therapy, not you. Secondly, you set up this expectation of a fun board game, and BAM! Knife! It’s called a misdirection, you wouldn't get it. You're supposed to be confused and a little scared, like I am now explaining it to you. Try to keep up. The joke is funny because she went from a simple game to something violent unexpectedly. You obviously don't get sarcasm, you simpleton.
