Buzzfeed's Nat Stopera must be really, really into Neil Patrick Harris and/or David Burtka. For Father's Day, Stopera has compiled a roughly chronological photo- and tweeto-graphic celebration of Harris's and Burtka's relationship, and of the couple's ongoing adventures in parenthood. Wow! It's pretty exhaustive! And thoroughly adorable. Harris, Burtka, and kids plainly have a lot of fun together. See how much here.
(Incidentally, Harris and Burtka appeared on OWN two weeks ago to talk about their family life. Watch that here.)
