He's making a video with Josh, they have to not laugh because if they do. You'll set off the shock collar on their necks, you hear even a giggle and you set it off but literally Mully going "DaAMmn" with his voice breaking then saying "Why'd my voice break just then? I'm 30 years old why is my voice still cracking bro? what the fuck? DaAMmn. What the fuck just happened? I watched a black guy mix bananas and sugar for a minute and my voice breaks" almost gets Josh to burst out laughing
