Randall Konerko, a 39-year-old database administrator looking for a new job in the field, was relieved to learn Monday that a letter of recommendation from his former employer makes no reference to the Dec. 11 balls-copying incident that led to his dismissal. 'Whew, that's a relief,' said Konerko after an interview with Luminant Worldwide. 'I was sure Mr. Alland would mention that whole thing, but, mercifully, he didn't.' Konerko has made a promise to himself never to engage in testicular Xeroxing, even if it's 2 a.m. and the office seems empty.
