"Who the Hell Said That!" ==> New South Park contest, at Comedy Central's website.
You're given a SP quote, you have to click on the character that said it. Sounds simple enough, right? The winner gets $500 worth of CC merchandise, probably enough to buy one of every SP shirt, too bad they don't have them in MY size. Twenty-five runners up win $50 CC gift certificates. Requires Java and Shockwave, I think. A few pointers:
Speed is the key. Each quote is worth 1000 points that quickly counts down to zero. Screwing up will cost you about 350 to 400 points each time. "Oh my God, they killed Kenny" is credited to Stan, not Kyle. Learn the locations of key characters in the picture, esp. some of the ones in the back row. Also, "key words" in the quotes can give you a clue to who said it, dude. Contest ends when the new season airs, 20-May-1998. Beware, it can be addictive. (More addictive than CartMan and StackUp anyway!)
I do NOT work for Comedy Central or any of its affiliates, etc. I just like this game, and didn't notice any names from the NG on the high-score list.
My best score to date is 214,980. Overall best score is 220,500.
