I've gotten almost everything, phishers using names of cousins, my dead brother, and others... all saying they were stuck in Madrid's hospital and needed cash for bail money... When I mentioned that said person was dead, the scammer gets scarce fast.
A few years back, I got a call about one call saying, "Microsoft's police will be arresting you in 45 min at your location, and will kick through any barrier to get to you". Ironic thing, when the guy said that, I was doing a one-off contract for a county's police department. So, I reminded him of that fact, and that the local PD wouldn't take kindly to people "kicking down barriers".
