Xtreme Sk8ters

 is a comic about skateboarders. Not much is known about it. Extreme Sk8ers has 2 characters: a stick person with a white helmet and one with a black helmet. The one with the white helmet always dares the one with a black helmet to do some sort of dangerous skating trick. The black one does the dare, gets seriously injured, and finishes with a punchline. In Diary of a Wimpy Kid: Do-it Yourself Book, the white-helmeted stick figure dares the black-helmeted stick figure to ollie over a rock, which is positioned off the edge of a cliff.
