Aussie hunk and maybe fiance to Miley Cyrus, Liam Hemsworth, has a goofy side -- and he showed it off on 'Jimmy Kimmel Live,' where he chatted about everything from 'Paranoia' to putting his money where his mouth is -- and to putting puke where his mouth is, courtesy of an American favorite, greasy fast food from White Castle!

"I watched a lot of American films," Hemsworth said of his Aussie upbringing. "A particular film that had a real impact on me as a teenager was 'Harold & Kumar [Go to White Castle],'" he laughed. "It had a deep impact on me."

"I think when it came out, I was 16 or 17, and my friends watched it religiously. It was like a bible," he admitted. "We didn't even know that White Castle was real then! We didn't have it in Australia, and we assumed that it was made up for this movie. And it wasn't until I came to the States that I found out that White Castle was a real place."

He revealed that when he moved to Hollywood, White Castle was his primary focus. "I spent the first year talking about it to people," he chuckled. "I said, 'Let's find a White Castle!' And there's none in L.A. -- here, they're all in the South and on the East Coast."

Thankfully, his 'Hunger Games' co-star (and romantic rival to Jennifer Lawrence's Katniss Everdeen) Josh Hutcherson was there to help.

"When I shot the first 'Hunger Games,' Josh Hutcherson took me to his place in Kentucky ... and he said there was a White Castle right by his house," Hemsworth said with a grin.

"So we planned on going there, and we bought three or four of these briefcases of White Castle burgers," Hemsworth revealed. "We took them back to his house, and we ate them. And then, about a half an hour later -- this was our first real bonding experience, me and Josh, this is when we became good friends -- we went out to his garden and we threw up together."

You know what they say: The pals that puke together stick together.
