Chris Pratt offered some unique insight into his home life while showcasing his rapping skills as well on Jimmy Kimmel Live.

The 45-year-old actor appeared on the ABC late-night talk show to discuss his new film The Electric State, which debuts on Netflix March 14.

Pratt shares 12-year-old son Jack with his ex-wife Anna Faris and daughters Lyla, 4, Eloise, 2, and son Ford, 3 months, with wife Katherine Schwarzenegger.

It seems his youngest son shares a unique trait with him – ‘a long ʙuтт crack’ – that has been making diaper duty quite interesting as he teased in an Instagram snap of Ford and Katherine last month.

He also teased that his daughter Lyla can be quite sweet… though quite menacing as well, revealing one of her wild threats.

The actor also unearthed a rap song he wrote more than 20 years ago while he was in his early 20s filming the TV series Everwood.

When asked if he’s been helping with the ‘swaddling and the changing,’ Pratt admitted, ‘He can deuce, I tell you.’

‘He didn’t get my eyes, but he got my long ʙuтт crack. That’s a genetic thing, and I’ll tell you, most of it goes up,’ Pratt added.

A laughing Kimmel added, ‘How do you know it’s long? I have no idea if mine is long,’ as Pratt insisted, ‘Oh you’d know if it was long.’

‘It’s one of those things you just know. You look around and go, “I think mine’s a lot longer than that,’ Pratt said, adding his dad, ‘had a long ʙuтт crack’ as well.

‘He was a contractor. My brother and I would go work for him. And plumber’s ʙuтт. That’s a thing, right? The pants hang down. He’d have his pants jacked up, he’d still have plumber’s ʙuтт,’ Pratt joked.

The actor also recalled how they were working on a log cabin and he was being ‘ornery and grumpy’ and his brother, ‘was taking handfuls of sawdust and dumping them in his ʙuтт,’ and even a 16 penny nail, but his father never reacted.

Kimmel also showcased a video that went viral back in 2014 of him rapping the Eminem verse of Dr. Dre’s Forgot About Dre.

‘I spent two years in a van, smoking weed listening to Eminem when I was 20, before I found Jesus, Jimmy,’ he said.

He gave the crowd some instructions on when to clap and even pulled out the gold chain from under his shirt before busting out a unique rap

He added, ‘And other kids learned biology at college. I was learning how to rap,’ adding he would record his own rap songs as well.

‘I had a season in my life. I was about 22 or 23. I was doing a television show for The WB in Utah called Everwood,’ he began.

‘But yeah, some 20 years ago. I had like a computer and a little studio set up in my office. And I recorded some tracks,’ he said, before Kimmel asked if he remembered any of the tracks he recorded.

‘Oh yeah,’ Pratt added, before Kimmel asked him to give them a ‘taste’ of some of his rap songs.

He gave the crowd some instructions on when to clap and even pulled out the gold chain from under his shirt before busting out a unique rap.

The crowd burst into applause after the song, as Kimmel added, ‘I feel like I don’t know you at all. Wow.’

Pratt added, ‘I’m putting my gold chain back. I feel like all the white people learned something tonight.

He also shared a strange threat from his daughter Lyla, who he says is, ‘very tough’ and while she can be ‘sweet,’ she’ll, ‘say something like “I’ll cut your eyeballs out.”‘
