This might've happened to you, but have your parents or a family member walked in while you were watching anime. Some of their comments might be funny, and some might make you embarassed.
One time when I was watching Castle of Cagliostro, my brother walks in and says "This doesn't look like anime! The animation looks like Scooby Doo."
The day I got Spirited Away on DVD, my mom was watching it with me. She thought that Haku was a girl. I told her he was a guy, but she still didn't believe me because she thought he sounded femenine.
You should see my dad everytime he sees me watching One Piece. He doesn't even see the subtitles, so he asks me "Do you even understand what they're saying?".
