what if peoples' elbows and knees were fused together naturally and we had to waddle around like that

like what if that was normal and we'd randomly have birth defects with non-conjoined joints and they would look like us and would be called freaks

would there be skin inbetween the upper arm and thigh? almost like flying squirrel skin flaps I guess. Would that remove our armpits? If there wasn't skin there, would there be MORE "pits" where the elbow and knee connects? Would hair grow there and it smelled?

how would we walk too would we be on all fours? Imagine a professor clamboring into a classroom through a doggie door and like still wearing a regular shirt and pants but they have buttons on the side so you can put them on and then he'd get on a lil stool and start teaching but his calves and feet were just dangling as he moved his arms around to explain things etc
