 When Alan Shore first sees Chelina Hall, he quips that when he last  saw her they were on Sunday nights, then they were canceled for a  while an now theyre on Tuesday nights. In reality, this is what  happened to the show "Boston Legal" itself. It debuted on Sunday  nights after _"Desperate Housewives" (2004)_ (qv), but was put on  hiatus when _"Greys Anatomy" (2005)_ (qv) proved to draw higher  ratings in the same time slot. It returned in the fall on Tuesday  nights.
