prize distribution center wanted money to release "prize money" las vegas, Nevada

i was contacted by the "prize distribution center" with the call back number of 866-430--3177, saying that i won a $50,000 prize.  I called back and was referred to someone named Jim. . . He spoke very fast and I asked hm to slow down and turn off the music in the background so I could understand what he was saying.  HE told me to "calm down" .. and then hung-up.  So much for my 50 k US$prize . . .He didn't get to me  for the fee. . .. Looks like the Nigerian scam has gone domestic.
