There have been several viral videos that were only 9 minutes and 15 seconds long. However, without more information, it's difficult to pinpoint a specific one.
Some possibilities could include:
1.
The 'Distracted Boyfriend' Stock Photo: A still image from a stock photo shoot became a viral meme in 2015. While not a video, it's worth mentioning as a viral sensation.
2.
'David After Dentist': Released in 2009, this 9-minute-15-second video showcases a young boy's hilarious reaction after coming out of anesthesia.
3.
'Keyboard Cat': Although not exactly 9 minutes and 15 seconds long, the popular viral video features a cat 'playing the keyboard' to a catchy tune. There are several versions of the video, but the original is not that long.
4.
'Charlie Bit My Finger': Another viral video, released in 2007, is only 57 seconds long but there are reports of a longer, unedited version that might fit the time frame.
If you have any more information or context about the video you're thinking of, I'd be happy to try and provide a more specific answer.
