Ex-Punk'd bros Ashton Kutcher and Dax Shepard reunite for a tell-all podcast. The two men discuss the MTV show, fatherhood, and aging among other things.

Robots And Sober Living

Appearing on Armchair Expert, Shepard's new podcast, the two dove deep into everything, from work to their famous wives, to robot sex. On his part, Shepard confirmed he wouldn't mind if his wife, fellow actor and Veronica Mars herself, Kristen Bell, had a robot boyfriend.

Kutcher also revealed his stance on sober living, describing himself as someone who doesn't partake in substances all that often, and who calmed down following college. This comes as a shock to fans of Kutcher's beloved stoner character, Kelso, from That '70s Show  but in reality, he wasn't really into any of that stuff.

Unfortunately, his relatively healthy lifestyle didn't aid Kutcher's hair loss over the years. He and Shepard shared their horror stories of thinning hair on the show.

"I started getting very concerned when I was 25, and that's when I went on the Avodart. And I think like, five years ago I stopped and I did really good for a year, and now it's thinning out," Kutcher said.

Splitting The Duties

The two men, both fathers in their 40s, advised they were trying to focus on the more important things in life rather than just appearances. Shepard, who has been married to The Good Place  star Bell since 2013, jokingly claimed he does most of the work raising their children.

"I really will say I do fifty-percent of the s**t with these kids. I definitely change more than my share of diapers, and I've exceeded what I think my father certainly did," he revealed.

Kutcher and his wife, actress and That '70s Show co-star, Mila Kunis, have a different routine.

"We both get up, every morning. In the middle of the night, we flipped it back and forth. Because she was breastfeeding the kids, she did way more than her share," he explained.

Over the course of their lengthy chat, Kutcher and Shepard also discussed their time on Punk'd and the difficulty with trying to avoid being typecast over their subsequent years in the business.

Following Punk'd and That '70s Show, Kutcher struggled to leave his comedic personality behind and play more serious roles, but he eventually took on Steve Jobs in Jobs. The critics didn't take to the film and Michael Fassbender subsequently blew Kutcher's portrayal out of the water in Danny Boyle's biopic Steve Jobs.

Shepard most recently appeared in the critically lambasted reboot C.H.I.P.S. opposite Michael Peña, which he also directed. In a hilarious turn, Bell starred as his bitter ex-wife, with whom his character is still struggling to get over.
