Called stating that he was Barack Obama, then said later, and hung up.

had the same number call me as well, saying they are the older brother of jake then asked who i was. said different name then they kept repeating themselves.

Since i live in Denmark and this call is from San Francisco, California... I didn't answer, but he left some random voices, like Hello, Who are you, with a very deep voice and computer mousepad clicks in the background. I believe this is prank calls but i am not sure

Left message on my land line answering machine.  Sounded like a random computer collection of Arnold Schwarzenegger's voice from his movies.  Someone with too much time on their hands.
