If you are looking for ransom, I can tell you I don’t have money, but what I do have are a very particular set of skills. Skills I have acquired over a very long career. Skills that make me a nightmare for people like you. If you leave me a voicemail, then that’ll be the end of it. I will not look for you, I will not pursue you, but if you don’t, I will look for you, I will find you and I will call you. This is a classic line from the movie Taken (without the violence). Your callers will always get startled at the threat initially but will surely leave them in jitters as they drop a message in your voicemail. This is a classic trick and one that is both funny and frustrating. Watching people continue to speak as if you’re there is funny. Make sure they know when to leave a message though.
