Heard a message from the "fake" IRS (202-386-0065).  I knew it was a scam so I called it back.  You can hear the number redirect to another number.  The person with a thick accent answered "IRS" and you can hear lots of noise and voices in the background.  I got snippy with him and he proceeded to use a profanity (THAT English was clear!) and I hung up.
