GRANBURY, TX–Moments after ending an on-the-toilet phone conversation with a female friend, Bruce Halpern realized Monday that his candor regarding his whereabouts may have been ill-advised. "That was dumb," Halpern said to himself following the call. "I've told lots of guy friends that I was taking a dump while talking to them, but Julie seemed pretty grossed out." Halpern made a mental note to explain the echo effect in future phone calls by saying he is in the garage.
