Fast National ratings for Tuesday, March 31, 2015.

"NCIS" delivered Tuesday's best numbers to lead CBS to an overall win, though an old-skewing debut for "The Doverkeepers" dropped CBS into a tie in the key demo.

In addition to "Dovekeepers," Tuesday's big premiere was "Weird Loners," which tanked aggressively, doing only a 0.7 in the key demo, serving mostly to make FOX look back with nostalgia on the numbers for "The Mindy Project." FOX also saw an ugly number for "New Girl," which celebrated its renewal by drawing only 2.3 million viewers and hitting The Mulaney Line.
