The Blacks got divorced .   Really ? Why ?   Mr . Black has been getting a little on the side .   Really ? I am surprised . He doesn't look like a guy who'd ever cheat on his wife , does he ?   No , he doesn't . Anyway , his wife found out that he has been two-timing for a long time .   Well , I am really surprised . By the way , have you done anything behind my back ?   No . The only thing I've ever done behind your back is zipping you up .
