LIBRARIAN: Hi can I help you?
ME: Yeah I'm looking for a book about–
LIBRARIAN: Clairvoyance?
ME: Uh... No.
LIBRARIAN: Dang that'll work one of these days.
@Lana Hahaha, and boy, when it does...
ME: Well, haha, funny story, I am in fact looking for a book on *blocking* someone’s clairvoyance.
@Lana I had a friend in college who actually did something like that. This was the old days, and there was one phone for the whole dorm. Long before caller ID too. His girlfriend called one day and he picked up and said "Hi Jane!" (not her real name). She was a bit taken aback, and then said "How did you know it was me. - wait - have you been answering every call for the dorm with 'Hi Jane!'?"
He had.
