I usually don't pick up numbers I know are spam. But every so often I feel like having fun.
"Hello, is George there?" (for some reason most of the calls are for George....and I have no idea who that might be.)
(my acting kicks in and I start crying) "George? Oh no!!! He died yesterday."
"OH! Oh! I'm sorry," says the person on the other end. He sounds distraught.
Still "crying" I hang up.
