The 47-year-old actor, who has Sid, 11, and Lazlo, 8, with wife Jenny Mollen, had long known he would have to discuss the moment his character in the 1999 comedy got intimate with a warm dessert with his kids and felt it would be better if he explained it himself.

Speaking on SiriusXM's "The Julia Cunningham Show," Biggs said, "They kept hearing about 'American Pie' and pie and [asking], 'Daddy, what do you do with the pie?' and I had to have a conversation with my oldest.

"I actually showed him the scene. Jenny and I talked about this, and we were like, 'We want to get ahead of this...'"

The "Orange is the New Black" alum continued, "It's my version of a sex talk, right? It's like, how much do you want them to hear from friends and other people at school, and how much do you want to control the narrative, and it was literally happening with ''American Pie.'"

Jason and Jenny made the decision to have the discussion with their children after an encounter with a fan.

He recalled, "[We were] walking in New York on the street and the boys were up ahead and thank god they did not hear it, but a guy walked past us all and literally screamed out back to me, 'Hey, it's the pie f*****,' and I looked immediately at the boys. They did not hear him, thank god."

Biggs admitted Sid was "embarrassed" to talk about the scene, but when he finally saw it, he found it hilarious, albeit "a little uncomfortable."

Jason said, "He guessed it, so in a way, I almost didn't control the narrative, but he wasn't entirely sure. But I wanted to ask him first. I said, 'What do you think happens?' I was just curious, and he actually guessed correctly. He was embarrassed to say it, very embarrassed, but I was like, 'Okay. Let me show you. Let me show you what happened,' and so I showed him the scene, and he laughed and laughed. He was a little uncomfortable for sure. He did say I was a good actor."
