Tiger Woods 99 had to be pulled from the shelves because of South Park!
Well, more specifically some prankster programmer from EA snuck in an AVI video file of South Park's "The Spirit of Christmas" onto the PlayStation version of the game.
While the video was inaccessible on the PlayStation itself, it was easily found if you inserted the game in the CD drive of any PC, you could easily access the video file. The Spirit of Christmas is the very first South Park clip ever made, even before it was picked up by Comedy Central and is basically an uncensored version of the show.
