Kaitlin Olson Says Her and Rob McElhenney's Kids Adopted Their 'Horrifically Inappropriate' Humor: 'You Can't Say That at School'

Kaitlin Olson's kids have inherited more than just their parents' genetics.

The High Potential star, 49, appeared on a Wednesday, March 12, episode of Late Night with Seth Meyers and spoke about how her sons Axel Lee, 14, and Leo Grey, 12, whom she shares with husband Rob McElhenney, 47, have started watching their parents' iconic TV show It's Always Sunny in Philadelphia.

As she notes that her sons "love" to yell "Dee's a bird" to her — a reference to a long-running bit with her character Dee on Sunny — Olson says she and McElhenney have tried to keep their kids away from the series, but have ultimately failed.

“My son, my 14-year-old, is…we’ve tried to keep both of them away from Sunny," she begins. "I had both of them while we were shooting the show. That’s how long it’s been. And we can’t keep it from him anymore."

Seth Meyers asks if they're young teens, which Olson affirms, saying they're 12 and 14.

“I would imagine a show like Always Sunny is catnip, even if your parents didn’t star in it,” Meyers says.

“We’ve tried so hard, but we walked in on him the other day, the 14-year-old, watching the episode where Mac builds the Ass-Pounder 4000 which is an exercise bike that has a penis coming out of it to motivate you," Olson says. "But it’s a ‘fist,’ but it’s not a fist.”

Meyers, laughing, notes that it's hard to discipline their kid for watching the show when Olson and McElhenney are behind it.

“Yeah, then I like pause it and go like, ‘Ahhh, um, we gotta give this some context,’ ” Olson says. “And then I don’t know what context to give it.”

Meyers then asks if they ever try to get away with things like comedy bits, since they're entering their teenage years.

“Listen, they’re both very funny. But at this age, the sense of humor they’ve adapted from us is just so horrifically inappropriate," jokes Olson. "We’re like, ‘Ooo! You’re so close! Like in a few years, you’re going to fine-tune that and be so funny, but you can’t say that at school.’"

"It’s really, it’s such a fine line. I mean, they make us laugh, but it’s a fine line," she continues. "I talked to my therapist about it, and she was like, ‘Okay, you can laugh, but what you need to say is, “Now, I think that’s funny, but let’s imagine you’re out in the real world. People don’t understand who you are. They might think you’re a rapist or a murderer.”’

"Oh my god, this parenting thing is a lot harder than I thought it was going to be," Olson jokingly adds.
