I answer my phone too. There aren't that many junk calls, and sometimes they are entertaining. Sometimes I don't recognize the name on the caller ID but it turns out to be someone I do need to talk to.
Today I got a call where a recorded voice told me I was the only one on the conference call. I hung up; end of conference. Yesterday I had one where a man with a very deep voice (they always choose someone with a deep voice) started out by telling me I am harder to reach than the top of Mt. Everest. I didn't laugh or respond. He then said he was from a police group. I told him I didn't believe a thing he said and hung up.
