Someone is on the Corner of Ward and Baker shouting: "I saw Bigfoot and the Loch Ness Monster in a Flying Saucer!!!!". Pretty soon there's a "Get Down To Earth" gofundme and the city is building a landing pad.
The prophet shouts "They'll be here at 6:00 AM on Wednesday Morning". The whole town assembles. There are signs - "Welcome" and "Get Vaxxed ASAP" and "Medical Freedom is your RIGHT!" and "Loch Ness Monster Free Bigfoot" and "Bigfoot Free Loch Ness Monster" and these protesters gather on opposite corners, and there are other signs that read: "Having babies would be bestiality" and "Take our love into the stars" and "We hope you come in peace and are vegetarian".
By Sunday evening the crowds are beginning to disperse. Somebody is overheard muttering: "Bigfoot AND the The Loch Ness Monster...how could I have been so gullible!!!".
