The PewDiePie’s Tuber Simulator meme originated from a recurring high-energy advertisement Felix Kjellberg played at the end of his YouTube videos starting in 2019. The ad became an overnight sensation and a viral copypasta due to Felix's enthusiastic delivery of lines like 'What?! You've never played Tuber Simulator?' and 'It's free, and that's a great price!' What started as a simple mobile game promotion evolved into a massive bait-and-switch joke within the YouTube community. Users often use the script to interrupt serious threads or as a nostalgic reference to the era of the 'Sub to PewDiePie' movement, solidifying its place as one of the most recognizable creator-driven memes in internet history.
