I was just about to post about this when I saw yours. I was watching some Tevin shit and saw this wax figure melting staring me down.
I refuse to believe that Dave doesn't have some kind of birth defect.
It's been said to death but the PC unboxing video is further proof of this. I have no doubt that he has some kind of discomfort, maybe even pain in his lower back. It happens when you spend the majority of your time sedentary. After a few months into the pandemic, I realized I was spending way too much time on my PC doing nothing when I started to have some mild lower back pain. I picked up a beginner's yoga routine and in less than a month, I was feeling better than ever. Dave probably goes from sausage mode on stream to sausage mode in front of his downstairs TV. He's just going from playing video games for "his job" to playing games on his phone.
I wouldn't put it past him to have Kat take out the trash because 'his back' prohibits him from straining himself.
I'd love to see some candid footage of Dave and his pet waddling around Kroger's, asking employees to lift items heavier than a couple pounds into the cart.
