Hey Pandas, What's The Funniest Thing You've Heard/Seen Someone Do When They Thought They Were Alone?

I usually wear headphones when I do dishes. (Important later) We had just got my cat, and she had a habit of keeping my mom up at night. I went to go to dishes and left my cat sleeping in a box. My mom thought I had my headphones on and went to the car and said, "Now imma keep you up while you try to sleep" Then she made this noise that sounded like this hfhghfhghghgjhg. And hobloo hobloo hobloo. It was hilarious. (Headphones were charging)
