I see this lady panhandling at Walmart everyday. I like homeless people. I am pretty sure they are time travelers from the future who have decided to stay in this time to escape the squalor of the post apocalyptic future. They are all being tracked by evil scientists using radio devices in their teeth. If you look closely you will see they are all missing their teeth. They pull them out to escape the prying gaze of science. You should give them money so they can stay here.
