MADISON, WI—Chimpanzees at the University of Wisconsin's Primate Laboratory are nearing completion of a two-year study on human-evasion response to hurled feces, sources reported Tuesday. "Our research shows that Homo sapiens experience extreme agitation and an urge to flee when pelted with baseball-sized lumps of primate scat," said Dr. Jingles, speaking from his research cage. "In 10 out of 10 cases, our test subjects retreated to the far corner of the room and screamed, 'Stop! Stop! AIIIIGH!'" Dr. Jingles first made his mark in science in 1993, when he earned a Nobel Prize for conclusively proving the deliciousness of bananas.
