WASHINGTON—A new study by the Federal Communications Commission has determined that as many as 81 percent of all calls made over pay phones start and conclude with uncontrollable sobbing. The report, published Monday, surveyed a wide sample of public telephone conversations, nearly all of which began with the phrase "Please don't hang up, oh God," and devolved into unrestrained bawling on the part of one or both participants. The FCC's report also confirmed that the remaining 19 percent of pay phone calls are wrong numbers caused by frantically misdialing one's parole officer, ex-girlfriend, bookie, or AA sponsor.
