\"Drinking coffee with Kaley this morning and 'To Kill a Mockingbird' comes on TCM. Watching Atticus, the 'perfect' dad, had me reflecting on all of the amazing men in my life. Men who took the time to share their wisdom, teach me VALUES, encourage me, support me, and keep me honest,\" he wrote in the caption. \"I'm so grateful to all of you, you know who you are. Happy Father's Day to all the amazing men out there. I couldn't be happier to join the club. Love you @kaleycuoco - thanks for all the dad swag, a beautiful morning and for being the best partner in the world.\"
