San Francisco residents who tried to complain about noise from the Nike Marathon's 5:30am start on the weekend were surprised to hear a woman tell them to "unzip that fly, baby." The city's 311 inquiry line had suggested people displeased by the early-morning music and amplified announcements call 800-RUN-NIKE, which turned out to be a phone sex line, the San Francisco Chronicle reports. The number for the real Nike complaint line is 866-RUN-NIKE. (More San Francisco stories.)
