The PSR is dumb
Because yesterday I was standing on the corner minding my own business and all of the sudden for no reason at all out of nowhere causa sui ex nihilo completely randomly my pants fell down and I got a fine for indecent exposure and now I'm on the register.
I keep my belt VERY tight, meaning the downward force of gravity was negated by friction along with the slight fluid bulge that results from the lack of blood flow. Therefore, the laws of physics provided no sufficient reason for my trousers to manifest at my shoes. Checkmate rationalists. Things just be like that.
