The Big Bang Theory is beginning to wind down its epic run, so the stars may be feeling an extra little something for their devoted fans. Kaley Cuoco literally cried tears of joy recently when a fan returned her wallet.

The 33-year-old posted several videos to her Instagram Story recounting the events.

“So I have had the strangest week,” the actress began. “It's been very up and down, very emotional to be honest. Probably just coming to the end of the show and, I don't know, lots of other things, but a really sweet thing happened to me a few days ago and I had to share.”

She continued, sharing the moment she realized her wallet was missing: “I became fully hysterical and didn't know where it was and traced my steps and was like, 'Oh my God, I left it there. It's gone. It's gone. I was crying. I was so upset. So I called (the restaurant) and someone had turned it in.”

The person who returned it is apparently a fan, because inside the wallet was a piece of paper that read “Penny,” the name of her character.

“Whoever did that, whoever is out there, thank you,” she continued. “I wish I could've met you. I would've given you all the cash in my wallet or whatever was in there. I really would've given you anything. I was so grateful that there was someone so sweet on this earth, and honest. And it didn't go unnoticed and I will never forget that because that could've been a very bad day for me.”

Cuoco concluded: “So there is good in the world.”
