Sometimes it really does pay to tell embarrassing and gross personal stories on late-night television. 

Liam Hemsworth, best known for his character Gale in the "Hunger Games" film franchise, recently appeared on "Jimmy Kimmel Live" and reminisced about a late-night eating binge he shared with co-star Josh Hutcherson. 

"When I shot the first 'Hunger Games,' Josh Hutcherson took me to his place in Kentucky. We're shooting in Nashville and we drove to Kentucky and he said there was a White Castle right by his house," Liam shared. "So we planned on going there and we bought three or four of these briefcases of White Castle burgers … And we took them back to his house. 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 really became good friends — and we went out to his garden and we threw up together."

Hemsworth added that he and Hutcherson each split roughly 90 burgers. 

Naturally, the White Castle people were delighted to hear that Hemsworth was such a huge fan of the fast-food chain. In recognition of his feat (despite the immediate consequences), they decided to offer the Australian actor $20,000 to the charity of his choice — as well as an official induction into the White Castle Hall of Fame.
