John Stamossays his preschooler is getting a lot of use out of his new favorite word.

TheBig Shotactor, 59, appeared onLive! With Kelly and Ryanon Wednesday, where hostKelly Ripaand husband Mark Consuelos served as the day’s hosts. During the chat, Ripa complimented Stamos on how he’s taken to fatherhood.

“I have to say that in all the variations of John Stamos I’ve known over the years, watching you become a dad has been my favorite one,” she tells the actor.

Admitting with a laugh that he “cries a lot,” Stamos says his 4½-year-old son Billy, whom he shares with wife Caitlin McHugh, is the “light of our life.”

Stamos then reveals that Billy’s “new thing” is that he “likes to say ‘poop,’ all the time.”

Stamos said Billy frequently says “hi poop” and one time, “I was trying to teach him a knock-knock joke” and he kept finding a way to insert the word.

“[He goes,] ‘knock, knock?’ ‘Who’s there?’ ‘Poop.'”

TheFull Housealum recalls Billy asking him what the word appropriate meant, which the little boy used as an opportunity to talk about his usage of the word.

“I said, ‘Well it’s not appropriate to say ‘poop’ at school or talk about poop at school,'” Stamos says.

“He said, ‘well what if I go to a poop school?'” Stamos says with a laugh, adding, “he’s smart.”

Stamos also shares that during a recent FaceTime call, he was saying goodnight to Billy and told him to go look at the moon while he, who was away from him that night, did the same.

“And then he said, ‘Daddy, I can see your eyes in the moon,’ and I said, ‘Son, I can see your eyes too.’ It was that beautiful moment, and I said, ‘I love you, Billy.'”

Equally heartfelt, Stamos says Billy responded, “I love you poopy.”
