‘I had bloody nipples,’ Ashton said. ‘I’m like what is happening right now. My legs were fine, but my nipples were on fire.’

Hilariously, David presented the Dude Where’s My Car actor with a set of gold nipple tassels for future use.

As to why he took on such a fitness challenge, Ashton told the host that he was running his first marathon to support his non-profit for Thorn, which fights against the sexual exploitation of children.

Ashton said he was training for the race on his Peloton treadmill when he decided to ask Peloton about making training a show to help keep him motivated.

‘I was like ‘hey what if we do a show in my basement where I invite friends to run with me and we bring a Peloton instructor and I interview people while we are running,’ Ashton said.

‘We’ve been shooting and we’ve shot like 10 episodes of this show with Natalie Portman, Kenny Chesney and with just friends, Chris Paul, that come over.’

David talked about going to Costa Rica years ago with Ashton to open up a casino.

‘I’m not even sure if it was a legal casino but they flew us down,’ Ashton said.

Ashton said he was nervous coming on the show when he heard David was hosting.

‘I was like this is the night I get cancelled,’ Ashton said. ‘Here’s why, we used to hang out before TMZ and the things that happened.’

David said the thing he liked about him was that he now only acted when he wanted to because he took care of his money.

‘I got really lucky, really early,’ Ashton said. ‘I’ve been investing the last ten, decade plus, I started investing in startups and it’s going very well.’

Ashton said he just got excited about investing when he wasn’t excited to go to work everyday as an actor.

‘I started to do this investment stuff and we built a firm,’ Ashton said. ‘We have a firm called Sound Ventures and invest in a lot of early stage startups.’

Ashton said he invested early on in AirBnb, Uber, Spotify, Robinhood and a bunch of others. Ashton said he thought it was funny now that actors make a public announcement when they decided to take a break from action.

‘You only have to call one person,’ Ashton said. ‘You have to call your agent.’

David said that Ashton was now married to Mita Kunis and had two kids.

‘I have the best wife,’ Ashton said.

David said he didn’t know if Mila was his best wife and asked him if she really made him give up his ticket for Virgin Galactic’s planned space flight.

‘I was supposed to be on the first flight on Virgin Galactic,’ Ashton said. ‘I bought a ticket for it. I had a ticket. But then we had kids and she’s like ‘do you want to be on the first flight or like the 50th flight.’

Ashton said Mita had sound logic.

‘Yeah, she made me give it up,’ Ashton said.

David then played a clip of Ashton from his new movie Vengeance writer by B.J. Novak. Ashton said it one of the best scripts he had read in a decade.

‘It’s about a New York podcaster that goes to the southwest Texas to basically prove to everybody how dumb they are,’ Ashton said. ‘He gets a lesson along the way.’

David asked him about his ‘pornstash’ in the movie.

‘My wife had to deal with this and it was all fun,’ Ashton said. ‘We’ve been together for seven years so when I brought home the mustache it was like ‘oh it’s a different guy.’

David also pointed out that Mila, who was born in Ukraine, had raised a lot of money for Ukraine.

‘We had met President Zelenskyy back when Trump was withholding capital from them,’ Ashton said. ‘We knew about that incident before it was public knowledge. I was like this is crazy. He’s blackmailing another country.’

Ashton said they became friendly with Zelenskyy.

‘When this whole thing kicked up we were like we have to do something,’ Ashton said. ‘We raised like over 30 million dollars to help.’

Ashton said he wanted people to realize that it wasn’t over.

‘It is the most important thing that is happening in the world today,’ Ashton said. ‘Because if this domino falls, it gets really ugly after this.’

Ashton there are many ways for people to help. He said Welcome.us allows people to help by adopting a refugee family.

‘There are 5,000 families in the queue to come to the United States,’ Ashton said. ‘We’ve got to do all that we can to continue to support.’

Not over: Ashton said he wanted people to realize that it wasn't over. 'It is the most important thing that is happening in the world today,' Ashton said. 'Because if this domino falls, it gets really ugly after this'
