Really bad recorded  voice claiming to be the IRS (and had to actually SAY that it was the Internal Revenue Service - just in case I didn't know what IRS actually meant.  Well since I write them a check every quarter to pay taxes - I'm pretty sure I know what IRS stands for).  Called 2x in 3 hours and left the recorded message that I was going to be sued by the IRS.  Bring it on baby!  What a joke.  Get a life.  Better yet - get a job instead of trying to scam people over the phone.  Low life scum.
