Well once I got a popup from browsing on some website, and it took a few hours to notice it. Here's how the whole thing went.
After browsing around, looking for some useless file online, I went to play Blockland. As I was building, I heard an ominous humming noise. It was very faint, but it almost sounded like bells ringing. I stopped building to try to get a clearer sense of what it was, and then I heard it. The words sounded like they came straight from Satan.
In a screamingly clear, almost monotone voice, I heard the phrase "Congratulations! You are the millionth visitor! Click here to claim your prize."
At that moment, I released a shriek that could shatter glass. I smashed my monitor on the floor, and kicked my computer until it shut down. I then unplugged the computer, our router, modem, phone, any form of wireless communication. After finally ridding the house of outside contact, I lay on the floor crying, and praying to Jesus to save my soul from this wretched thing that was The Popup.
