Betty White offered a solid official debut for NBC's prank show Off Their Rockers. After a special premiere in January, it earned a 1.8 rating with adults 18-49.

The struggling freshman comedy had a steady 0.9 then fell to a 0.7 for its finale, a series low. Rock Center With Brian Williams was steady with a 0.8 at 10 p.m.
