Cat Owners of reddit, what predicaments has your cat gotten into?

I walked into the kitchen once, passing by two double glass doors leading to the patio out back and thought I saw something at the door. I did a double take and he was sitting outside looking in, right up against the door. Swear my heart stopped for a second. He was very much an indoor cat and showed zero interest in going outside, at least none that I ever saw. No clue how or when he got out.
