38. Lorelai and Rory Gilmore, 'Gilmore Girls'
Take the rapid-fire dry-humor patter of an old-school screwball comedy, transfer it to the mouths of a single mom and her teenage kid, and you're on your way to conjuring the magic of the parent-child partnership that made Gilmore Girls run. Lorelai and Rory showed that when it comes to mother-daughter dynamics, learning from and leaning on each other need not be mutually exclusive. We can't wait for the Netflix reboot.
