I looked up how to spell "lewd" for Penumbra Wiki (in reference to Red's posters at the end of the first game), and then later on I wanted to do a reverse image search on something. I decided just to go back oo that tab I left open, click Images, and then click the reverse image button. Immediately after clicking Images, I thought "Wait stuff, my family is here and it'll be showing "lewd" images." Luckily I broke my Firefox window just in time for no one to see what I saw for a split second.
Moral of the story: Careful what you Google for, because if you hit Images, it'll probably be full of research.
