I'm concerned because my knees are crunchy. I'm about to Google "crunchy knees".
@zoohypothesis It’s called crepitus, and unless you’re having pain with it, it’s a fairly common and harmless condition. I’ve had it in my knees basically my entire life. Used to creep out my mom when I walked downstairs.
@zoohypothesis Web MD will advise that you have testicular cancer.
