Behind the laughs and iconic moments of The Big Bang Theory, there was one unforgettable—and utterly silly—incident that had Johnny Galecki and Kaley Cuoco questioning their future… well, at least for a minute. The infamous “Tuna-Gate” saga is a must-hear story from behind the scenes that shows even the best friendships have their quirky battles!
During an interview for The Big Bang Theory behind-the-scenes book, both stars revealed the hilarious truth: a simple tuna fish lunch sparked a fight so ridiculous, they joked it almost changed their dynamic on set.
Here’s what happened: Johnny was preparing for a theatre role and needed to stick to a strict diet. His dietician recommended tuna fish, which he brought to set for lunch. But the smell? Kaley described it as “horrendous.” She just couldn’t handle it and asked Johnny to take his lunch outside. Things escalated when Kaley even roped in Jim Parsons for backup—but Jim simply shrugged and said, “I don’t care about it.”
The tension grew, and Johnny finally snapped, “Is that how you talk to me? I needed my food!” 🎭 The argument over something as silly as tuna was so intense, they couldn’t help but laugh at how ridiculous it all was.
Despite this tiny on-set battle, Johnny and Kaley admitted that after over a decade working together, their friendship is rock solid—and they always have each other’s backs, no matter what.
✨ Tuna-Gate reminds us that even the funniest, closest friendships have their moments of chaos—sometimes it just smells like tuna!
