Stephen Amell has probably already won you over with his role as Oliver Queen on "Arrow" as a world-class vigilante, friend of The Flash and reformed playboy. But IRL Amell is so much cuter than his onscreen counterpart. I mean, Oliver has his sweet moments, too -- basically, every scene with his sister, Thea, or his current flame, Felicity, is laced with so much cuteness, we die every time.

But Amell, in addition to being ripped AF, is a husband and the undisputed champ when it comes to the Father Of The Year category. This weekend, he posted a pic to Instagram that made the rest of the world take note of his impeccable father-daughter moments.

But his Instagram is littered with tons of evidence that Stephen and Mavi Amell are the world's cutest father-daughter pair.

Preschool prep is never to be overlooked

A good father sets aside time for some beachside bonding

He teaches Mavi that mean-muggin' for the camera is a valid form of expression

And that you can never be too cool to dress up for Halloween

Swim lesson basics are a part of the Amell Daddy 101 Handbook

As is the all too important lesson on not drowning

Stephen Amell knows that you have to teach 'em the value of a dollar

And that important heart-to-heart talks are the foundation of a great bonding experience

Thanks to her dad, Mavi can now truly appreciate an excellent wardrobe

Lazy Sundays are good, but lazy ~any day~ is even better

Another important daddy-daughter how-to: Looking cool AF at the pool

Quality Instagram posts are a must because you're not ~basic~, you're an Amell

And fountain fanfare is always appropriate and always warranted

The faraway pouty stare is always guaranteed to win you a hug from dad

And shoulder top view is always the best view

Mavi has already perfected the side eye and Papa Amell has already accepted it!

But the most valid lesson is always good kicks are everything

And "Batman" kicks are even better.
