Filmmaker Vincent Gallo has shocked The New York Post by calling them to gloat about giving movie critic Roger Ebert cancer.
Since that time, Ebert has been diagnosed with the deadly disease, and Gallo got his assistant to call the paper to brag about his prediction.
His assistant reportedly told them, "Vincent just wanted to let you know that since he put a curse on Roger Ebert, he has gotten cancer."
Look at his picture and tell me you don't believe it.

Wow, this actually works and is sort of cool!
