On Tuesday's Jimmy Kimmel Live, the 36-year-old actress reacted to her husband telling a story while on the late-night show in May, about how he came to gather his sperm sample for a routine checkup following his vasectomy.
The 41-year-old Parenthood actor revealed that he ran out of time to "procure" his sample, so he ended up having to get it done while in traffic. "I brought a Mason jar with me that I rinsed with extra hot water -- sterile, I think," Shepard joked. "This is the God's truth. I had to drive cross-town, rush hour -- thank God there was heavy traffic on Laurel Canyon, so it slowed down enough that I could [multitask]. I literally masturbated on Laurel Canyon in heavy traffic. WATCH: Kristen Bell Gets Talks Getting Intimate With Dax Shepard -- 'We Slot Time for Sex'
While some wives may have a problem with their husbands sharing such a personal story about "gathering the specimen" on television, Bell was totally fine with it. "I'm not going to attach anything negative to it," she said. "We're people that like embarrassment."
Bell even added to the story, quipping, "You have to check the batter to see if it's still active."
Kimmel asked what other TMI stories the couple might have, which led Bell to admit, "Someone in the household is almost always nude."
In May, the Bad Moms actress confessed to ET that her date nights with Shepard are not as wild now that they have two daughters. Bell shared, "When we put the kids down and we look at the clock and it's like 7:43, we're like, 'Let's go to bed!'"
