I get this call from different numbers (and different area codes), but it's always the same recorded voice.  A guy (really excited) starts rambling on about winning some football games and proceeds to tell me how I should let him pick games for me, etc.  I get the calls the day of or before football games (Monday night, sunday, saturday, new years, etc.).  If it was the same number every time, I wouldn't answer, but since it's always different, I go ahead and answer.  I'm tempted to stay on hold so that I can actually talk to a person and waste their time in return, but I don't.  How can I get rid of this pest?  It is driving me crazy!
