I laughed at your cow photo! :-) And I understand the laughing at someone else's discomfort. Even if I don't do it much, after my brother and I laughed uproariously at my mom trying to open a sliding screen door and having it fall off the track and bean her on the head. She was really, REALLY upset. So now I'm too guilty to laugh. Unless it's in a movie, and they don't know I'm laughing. Then it's okay. :-)
