Manny Pacquiao's Greatest KO

Manny Pacquiao's Greatest KO is 50-second screamer video uploaded to YouTube made by user simonsay15.

Video
It shows the footage of Manny Pacquiao's fight against Thai boxing champion, Fahsan Por Thawatchai in Taguig, Philippines in 2004 dubbed as "Yanig sa Taguig" (lit. Shocks in Taguig). The Eminem song "Like Toy Soldiers" played in the background. It starts with a text to look at the opponent's (Thawatchai's) feet and lift off the chanvas from Pacquiao's punch. the viewer must not blink. otherwise, it will be missed. That footage starts playing normally. but after at a 37 seconds mark, a picture of Regan MacNeil from The Exorcist changing colors pops up with the same scream sound effect used from the K-fee commercials. The video then resumes to normal and Thawatchai is KO'd. then the video ends with text saying: "Did you see it?".
