Funny thing, I actually can put a Switch in one of my pants pockets. I have a pair of slightly oversized black pants, and the pockets are huge. It's a little awkward with a Switch in there, because it goes down almost my whole thigh, so I end up walking a little stiff.I know it's a joke, but i probably could, (biggest thing i've put in them was a Dualshock 4), if i ever see one in real life i might try, however, most people can barely fit their phones, and the 3ds has more or less the dimensions of a thicker smartphone (when folded)
