A scam? What do you think?

I had a phone call yesterday on my cell phone. After several hellos back and forth because of a bad connection a young sounding man, in very broken English, informed me that the US government was going to award me $9,000. Lucky me!  Being the skeptical person I am, I laughed and hung up.  Then I looked at the caller ID and it read Washington, DC.  I thought that was kind of a cute touch.
