It's awful how many scams there are, and how many people fall victim to them, but on a somewhat lighter note, my grandma (age 84) loves to play games with them when they call. They'll say "it's me, your grandson, I've been arrested in [foreign country] and I need money!" and she'll go "Which grandson are you? I can never keep all you dang kids straight." Or she'll pretend to get mad and tell them they owe her money! She doesn't typically answer the phone for unknown numbers not in her area code, but that doesn't filter out all of them. She's sharp enough that I'm not overly worried yet, though.
