However, there could be multiple viral videos with that exact time duration. I'll provide a few possibilities.
1.
Elon Musk's Tesla Autopilot Demo: In 2015, Elon Musk posted a 40-minute, 42-second video showcasing Tesla's Autopilot feature. The video demonstrated the capabilities of the semi-autonomous driving system.
2.
The 'Charlie Bit My Finger' Video: While not a full 40 minutes and 42 seconds, the original video was 28 seconds long, but a longer version of the video was posted.
