Phony scam calls from Microsoft shutting down my computer unless...., the IRS seizing all my property unless..., Auto Warranties on long gone vehicles, vacation timeshares I have won that have hidden fees more than the hotel room would cost, non existent student loans I owe money on, etc. If I have time, and now I have more since retired, sometimes will eff with them. Usually let the answering machine screen them and usually no message. Sometimes I begin by thanking them for returning my call, which confuses hell out of them. When they ask my name I say, Bond, James Bond. The dog seems to enjoy "talking" to them too as best I can tell.
