called "Au Revoir Mister Ed!"; a similar send-off for The Donna Reed Show, which ran on the channel for nine years beginning with Nick at Nite's July 1985 debut, also ran that year. My Three Sons was sent off the night Daylight Saving Time ended in October 1991 with a marathon called "Nite of the Setting Sons," permitting two extra episodes in the marathon due to the one-hour time shift. During the summer months from the mid-to-late 1990s, the channel for a while ran a program block called "Vertivision" (later known as "Block Party Summer"), during which a different series was shown in a three-hour block each night of the week. In its first year, network promos referred to the nights featured in the special lineup as "Mary Mondays" (for The Mary Tyler Moore Show), "Lucy Tuesdays" (for I Love Lucy), "Bewitched Be-Wednesdays" (for Bewitched), "Jeannie Thursdays" (for I Dream of Jeannie), and "Sgt.

Another well-known lineup was "A Whole Lotta Lucy" block which ran on Saturday nights from June 4, 1994, to May 3, 1996, which consisted of I Love Lucy, The Lucy Show and The Lucy-Desi Comedy Hour, which were all airing on the network at that time (a similar block aired on Saturday nights from 1996 to 2001, featuring only I Love Lucy and The Lucy-Desi Comedy Hour). In the mid-1990s, another Saturday night programming block titled "Very, Very Nick at Nite" centered around a different theme each week, such as "Very Very Mary" with four classic Mary Tyler Moore Show episodes. In summer of 2008, Nick at Nite aired a marathon called Battle of the Sexes, which featured
