My roommate and I were once passing a psychic's shop when the guy was trying to lure in customers. He said the usual patter about finding out about our futures then said, 'Find out why your hair is blonde!' We had to cling to each other to keep from falling down laughing, because the answer was, 'L'Oreal!'
I used to work as a 'fortune teller' renfaires. For 90% of my customers, it was all in good fun. On one memorable occasion, a young lady slipped into my tent, handed me $10 and told me how she was about to bring her friend in to keep her occupied for a couple minutes while they arranged the surprise of her fiance, who she thought was still overseas, showing up in full period dress. I went to town spinning how 'romance was in the air' and 'she was about to meet someone very special'.
Some of the customers were special snowflakes who just wanted justification for their perceived specialness and to be told how right they were and how they deserved everything they wanted. One lady got mad and demanded her money back because I didn't tell her she was the reincarnation of 'Morgana' which she apparently felt should have been self-evident, and another threw things at me when I said that there were no witch burnings during the Salem Witch trials because her 'past life' had been burned at the stake there.
It was pretty good money. I quit because of the folks who actually believed - folks grieving a missing loved one who wanted to be assured that their loved one was happy and would be returning soon, folks who wanted me to make contact with a deceased love one so they could have closure of some kind. I couldn't give them what they wanted, and I wouldn't scam them, so I quit.
