A disturbing number of her listeners describe moments in which their first realization that they weren't alone in the bathroom was a faint tickling sensation on their bare bottoms.
Ms. Crwys-Williams said her favorite caller was a woman who had been taking a bath with cucumber slices on her eyes. She felt something scratchy on her sponge as she soaped herself, and ran screaming into her garden stark naked. A brave neighbor, hearing the screams, immediately vaulted the garden wall.
Professor Crump said she can top that. A woman who visited her museum "to talk about some other bug," she said, had a daughter who woke up to find one on her pillow, staring at her.
"She screamed, and it was so startled it jumped in her mouth," she said. "When she pulled it out -- you know it has those barbs on its legs -- one of them got stuck. She had to go to hospital."
