If you think Richard Castle is the world's best dad, you obviously haven't met Molly Quinn's real-life pops. According to the 18-year-old actress, he's Castle "to the power of 10."

Yesterday, Molly shared an adorable picture of her and her dad napping side by side 18 years ago, when she was just 8 months old.

"Happy Father's Day Dad. Us 18 yrs ago, 2 peas n a pod. #peapodbond," she wrote.

She also gave a shout-out to her beloved TV dad, Nathan Fillion, and Castle show creator, Andrew Marlowe.

"Luv 2 @NathanFillion & @AndrewWMarlowe also."

Aw, Molly is one lucky girl!
