The Cancer Prank 

A prank in which one person (the attacker) approaches another person (the victim), saying, "I was reading a copy of Scientific American, and, apparently, scientists have discovered that if your hand is bigger than your face, you have cancer." After hearing this, the victim will lift their hand to their face, attempting to see if they have cancer. Then, the attacker will smack the victim's hand into their face, resulting in a throbbing nose and tons of laughter.

The Cancer Prank

Don: "Hey, Jon, I was reading a copy of Scientific American, and, apparently, scientists have discovered that if your hand is bigger than your face, you have cancer."
Jon: "Really???"

*Jon lifts hand to face, and Don smacks Jon's hand into his face*

Don: "Ha, ha, ha!!!"
Jon: "Ow, ow, ow!!!"
