Funny you mention this. We bought a 2008 Yukon XL Denali from a dealer in Clinton, IN back in December of 2017. It belonged to the mother of the guy who owned the dealership. We were thinking "Oh, this is a grandmas car, should be in pretty decent condition." When we got it home and started really spending some time in it, one of the kids mentioned that it looked like there were foot prints on the ceiling that only showed up as shadows. if you ran your hand along the headliner, there were barefoot foot prints pressed into the headliner. She must have been one hell of a limber grandma!
