[Editor's note: In celebration of the holidays, we're counting down the top 12 Flavorwire features of 2012. This post, at #6, was originally published April 11.] Ladies and gentlemen, brace yourselves for a good, old-fashioned SAT-style analogy. Ready? Creed from The Office is to Hello Kitty as Don Draper is to ________? If you answered “Oscar the Grouch,” you win! Confused? Don’t fret — it’s easy to assume that these fictional folks are unrelated when, in actuality, they celebrate their birthdays on the same day. Fun fact, eh? On that note, so do Rocky Balboa and Seth Cohen, the Weasley twins and Bart Simpson, and Superman and Jerry from Parks and Recreation — and we’re just getting started! After the jump, we’ve made a series of monthly timelines charting hundreds of fictional birthdays from TV, film, literature, video games, and beyond. Of course, not every day can be Liz Lemon’s or Rambo’s birthday, so a few of us might find that our character birthday soul mate is an obscure anime character or a toddler on a soap opera, but hey, that ain’t so bad. Click through for upwards of 365 character birthdays, then hit the comments to announce your newfound birthday twin.
