I guy I know was in a roadside cafe in Vietnam and the waitress came to him and started saying something urgent in a loud voice. He understood nothing and was saying "It's OK, it's OK" and making patting down motions with his hands - then he saw on his shoulder the largest, meanest spider in the whole world ever.
He squealed like a girl as he flung it off then, apparently, danced around waving his hands.
Really flew the flag on that one.
