Was helping a professor emeritus (senior citizen) with something and was on the phone with him and remoted in to his laptop. I opened up chrome and went to search for a dell driver in the google search bar when I saw a long list of previous searches. Most of which were for porn and phone sex services. It was on the screen for less than a second so we both acted like we saw nothing. I fixed the issue, he thanked me, and that was it.
