Have you ever been pranked?

Yes, but I don't really consider it an awful prank. My friends know I'm a real scaredy cat and I told them they better not show me anything scary. But one of them insisted I watch this video of a dancing little girl in Facebook. I told him before I watched it that I don't want to see anything scary but he promised me it wasn't. So I watched it... and then this gruesome face popped out and somebody pushed me lightly at the back. We were at work and I screamed so loud, it was a good think we were on break. He laughed and said sorry but I did pull his hair really hard since I was standing behind his seat.

when i was a kid i got pranked by my cousins... they said that they can summon a demon with a ritual, as a kid i'm very curious how to do that so they prepare a ritual in a dark room. They prepare 4 pieces of ceramic noodle cup filled with water arrange in a circular pattern facing north, east, west, and south. In the center there's a candle. After they ready they let me in to the ritual room. then we sit in front of each cup and start the ritual by putting our hand in the water inside the noodle cup, cast some spell, lift the cup, rotate it three times and put the cup down and use your hand to wash your face so you can see the demon. after doing that i was told to see the demon inside the mirror behind my back, suddenly when i see the mirror, i see my face all covered in black stain. And they all said "see, there's a demon in the mirror".... damn, i got pranked. It turn out that while they preparing the ceramic noodle cup, they burn the lower side of the cup with the candle so it leave a black burning mark on the ceramic cup. then they set the room to dark so i couldn't see the cup. When my hand rotate the cup three time, the black burning mark from the cup transfered to my hand and when i wash my face with my hand, the black stain transfered to my face....
