Well, my stepdad runs all our internet traffic through a server in our house and checks the connection log daily, so he's more than aware of everything I look at when I'm not at college. One day, when my girlfriend was over, he said something like, "Well, if you want to talk about the internet, we can do that later, when it won't embarrass you." Little does he know that my girlfriend and I are completely open about porn and masturbation, so I responded, "Oh, the porn? Which ones are you talking about? Lesbians or masturbation?"
He gave me a weird look, my girlfriend smiled and kissed me, and we went back to my room.
