Dean Jones, essentially says "This call is for you. I am calling about the IRS - the Internal Revenue Service. I am calling about the lawsuit filed against you by the IRS. It is important the MINUTE you receive this call you call me back.If you do not call me back..." It ends with something to the efffect, "if you don't call me back, I wish you well in this terrible fight/endeavour," ... or some such.
I'm calling the IRS.
