Received a call from this number at my boss's direct line. After identifying myself, there was silence, then the line disconnected after a few seconds.

I have received many calls--always starts with "you are harder to get a hold of than trying to get my teenage daughter to clean her room." I'm not hard to get a hold of, so that's a dead giveaway. The last call started with "You are harder to get a hold of than it is to get my grandson's hand out of the cookie jar." Usually I just hang up. Once I listened for a bit. She gave me her breast cancer pitch. I interrupted and said that I don't have any money to spare. She said "okay, but may I ask you one question?" And then she went on with "did you know that ____ people die every year from breast cancer?" It wasn't a question. So I hung up.
