I'm ashamed it took me this long in life to figure this out, but the best way to make time spent in the waiting room at a doctor's office go faster is to bring a good book.  The crappy magazine selection usually doesn't help, but a book that you pick out and that you're interested in magically makes time disappear.  Plus you can totally shove it in your doctor's face when they call you into the back room and you don't respond right away because you're thoroughly immersed in your book.  Take that, stupid doctors. #entertainment
