John Stamos almost watched "Fuller House" while giving a sample in a fertility clinic

John Stamos had a hilarious time in a fertility clinic.

The 55-year-old actor arrested by Busy tonight Monday, where he told all about his trip to the fertility clinic, when he and his wife Caitlin McHugh were trying to start a family.

"It's an absolutely true story, and I was waiting to tell this story," he told Busy Phillips, the host of the series. "[We were] trying to get pregnant and we had to do something, we had to go to a fertile place and I had to go and give a sperm sample. "

"I went to this little room where they go," Go on … "And they said," If you need stimulation, it does not matter, there are videos and there is a television here, turn on the thing, "he continued." I turn on the TV … and it's on Fuller House. My hand to God. "

"I think if I'm going to masturbate, it will be my old self, not the new one," he joked.

Despite the embarrassing moment, everything went well, Stamos and McHugh, 32, welcoming their son Billy in April.

"I waited a long time. I'm 72 now, then, "joked Stamos about fatherhood. "I started going there. I've been on TV with babies. And I feel as if now I'm holding it, someone will come and take it. I do not allow the word "cut" to be pronounced at home. "

Stamos continued to want to be a father by telling Philipps that it was the "best time" of his life.

"It's so beautiful. This is the ideal time, "he said. "I am happy to have waited to be able to totally devote myself to my wife and my child and forget about myself, because you are tired of yourself after a while, n '. is this not?"

Billy, 7 months old, brings a lot of love to Stamos 'house, largely thanks to his namesake, Stamos' father, William Stamos, who died in 1998.

"My wife was so kind to let me give her the name of my father, Bill. Billy, he says. "It was my dad's birthday yesterday, and he's been gone for a long time, so he only has his energy left at home and says his name reminds him of all that, and that's the best time of my life."
