If Danny Tanner ever goes missing, you can count on Jesse Katsopolis to go find him.

On Tuesday, John Stamos wrote a touching birthday message to Bob Saget and shared it on his Instagram.

"You're my Nemo," Stamos's message began. "If you get lost in the great, big ocean, I'll find you. Happy Birthday Bobby, I love you."

Saget, 60, replied with an equally as sweet message to Stamos, 52: "Love you John. Thank you my brother." Then the birthday boy posted a hilarious message to his longtime friend.

Ever since costarring on Full House, this cast has held a very tight-knit relationship that has carried on into their new spinoff show, Fuller House.

Candace Cameron Bure, 40, also got in on the action and shared her very ownbirthday message for her TV dad: "I love this man with all my heart. You have always been one of my best friends, someone who understood me, someone who got me and has always been there for me. You know I'm always here for you. Happy birthday @bobsaget. Love you so much."

Fuller House is currently streaming on Netflix.
