Mere months ago, we all were in agreement that Blake Lively and Ryan Reynolds were beautiful people. Gorgeous, glossy-haired, fit, perfectly-tan-but-not-in-that-obnoxious-way-Chris-Pratt-was-in-Jurassic-World people whose offspring would be a formidable genetic combo of perfection. What we’ve learned in the short time that Blake and Ryan have joined Instagram is that they’re pretty effing funny too.

Topical case in point = the Preserve founder’s Instagram to celebrate hubby Ryan’s first Father’s Day. In a pretty, monochromatic (Valencia filtered?) waterside moment, Blake posted a photo of Ryan carrying their little baby James with the caption: “Happy Fathers Day!!! … @vancityreynolds Since the day our baby was born, I’ve felt so strongly in my heart that you were most likely the father. #ILoveYouSoMuchItsSilly”

This photo has a lot happening in it. From a quick glance, it’s just plain adorable, the caption is sweet as heck, but when you look closer you’re like, “Oh, wow, look at Ryan Reynolds’ off-duty dad-in-sneaks look, it’s so ‘just taking a stroll with my wife and daughter, no biggie’ and yet — those arms. That smile. I almost don’t care AT ALL that he’s wearing cargo pants.”

The Instagram, while cute and all of Ry, is also a sly first (okay, one of the first — Blake’s first) photo of James, Ryan and Blake’s bundle of undoubtedly cute joy. Sure, it’s only her polka dot socked tootsies, but what’s cuter than baby feet?!

And h/t to Blake for proving that an all-in-good fun paternity joke is the ultimate dad joke. See. Told you she was a hoot.

Happy Father’s Day, y’all!
