Two men ? including one who wore an adult diaper during his disruptive dash ? were charged Thursday with misdemeanors for running across the outfield during an A's game last month, authorities said. Kali Wilson, 28, of Oakland and Michael T. Robinson, 24, of San Francisco were charged with violating a city ordinance prohibiting people from illegally entering a part of the stadium "before, during or after" an event such as a game, authorities said. "We wanted to make the crowd laugh," Wilson said in a telephone interview Thursday. "All the fans got a huge chuckle out of it."
