My mom works with an actual Wiccan/New Age spiritualist lady and one year they had a Halloween party and asked my mom to dress up like a Gypsy and read people's fortunes...just as a gag mind you. My mom does not believe in or know much about such practices so she was just hamming it up and telling people whatever popped in her head.
Then this lady...the Wiccan, comes over to her little area...furious, and starts lecturing her about how offensive and wrong her readings are. She did not talk to my mom for over a year after that but now they are friends.
The irony was that while my mom was doing her joke readings at the party, the witch lady was giving her allegedly 'real' readings and taking things quite seriously. A ton of people came up to my mom afterwards to tell her that her readings were at least as accurate as the witch's.
