In an age of social media friends, only the B-est of Fs can stand tall IRL to claim the title of "best friend," y'know?
A true best friend is not only text-able, but also *gasp* potentially call-able (and callable!). Like, say your car breaks down at 3 a.m. and you need a ride. Who are you going to have come help you? Your insurance agent? Pshaw. Patti Smith at State Farm already has a best friend, and it ain't you.
Of course, there's lots more to being a best friend than simply bailing someone out of trouble. I mean, I'm not sure what those things are, so we collected lots of comics to tell us.
What? You love us for supplying you with 15 National Best Friends Day comics? Think nothing of it. After all, what are friends for?
