Manny Pacquiao's Greatest KO

Manny Pacquiao's Greatest KO- a 50-second Youtube screamer that 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" is played in the background. It starts with the text that tells the viewer to look at the opponent's (Thawatchai's) feet and lift off the chanvas from Pacquiao's punch. It also says that the viewer must not blink. Otherwise, it will be missed. That footage starts playing normally. But when the video reaches 0:37, a picture of Regan MacNeil from "The Exorcist" changing colors pops up with a loud scream. The video then resumes to normal where Thawatchai is KO'd. It then ends with the text "Did you see it?".
