"The Big Bang Theory" star Kaley Cuoco-Sweeting got a cuteness overload on Thursday’s "Tonight Show," joining host Jimmy Fallon for a "Pup Quiz" and ending up with a lapful of Golden Retriever puppies!

"Oh my god, I can’t take it," Cuoco-Sweeting exclaimed before the quiz -- in which a correct answer wins you an adorable puppy to hold -- even began.

Cuoco-Sweeting, who at times got emotional, took an early two puppy lead and immediately became distracted by the adorable fluffballs in her lap.

Fallon won the next "Double Puppardy" and tied things up at two puppies apiece, but Cuoco-Sweeting took a "Double Puppardy" of her own and was overcome by the adorable puppy pile.

"I could die," the actress gushed. "This is it for me."

"The Big Bang Theory" star was reluctant to end the game with "Final Puppardy," but came the closest to correctly guessing the age of the oldest goldfish (43 years old) and won all of the puppies.

"Pup Quiz" is a relatively new "Tonight Show" game. Fallon debuted it last month with guest Salma Hayek, but based on sheer cute factor, we have a feeling it will become a regular.
