Har Har Tharsdays

Har Har Tharsdays (formerly New Thursday Nights and CN Thursday Nights) is a former Cartoon Network block that featured new episodes of Cartoon Network original series. It ran from March 6, 2008 to April 1, 2010.

History
The block started out as New Thursday Nights, and began at 7:30pm on Thursday nights. The block's first schedule consisted of:
 * 7:30pm - a new episode of Camp Lazlo
 * 8:00pm - a new episode of Chowder
 * 8:30pm - a new episode of Foster's Home for Imaginary Friends
 * 9:00pm - a new episode of George of the Jungle

This schedule stayed the same until in late April (before the block's name was changed into CN Thursday Nights on April 3rd), when My Gym Partner's a Monkey began airing at the 7:30pm replacing Camp Lazlo which had finished airing new episodes. Also, the 9:30pm time slot was used to air new episodes of Chop Socky Chooks. In May, Out of Jimmy's Head aired its final episodes in the 7:30pm time slot, replacing My Gym Partner's a Monkey.

On June 5, 2008, the block was renamed Har Har Tharsdays. The big changes made to the block were that the block lost the 7:30pm time slot and instead started at 8:00pm with a new episode of Chowder. Foster's Home for Imaginary Friends got replaced by The Marvelous Misadventures of Flapjack at 8:30pm, and George of the Jungle was replaced with Total Drama Island at 9:00pm. Also, Chop Socky Chooks was replaced by Johnny Test at 9:30pm.

On October 2, 2008, 11-minute episodes of Thumb Wars began airing after Chowder and The Marvelous Misadventures of Flapjack. That broadcast was called Star Star Starsdays. Scare Scare Scaresdays started the following week with an hour of Goosebumps (replacing Total Drama Island and The Marvelous Misadventures of Flapjack) but everything else stayed the same. The next week also had another change when Johnny Test was moved off the block and replaced with premieres of Halloween specials. In November, 6teen, a new show to the network replaced Johnny Test. In March 2009, Total Drama Action debuted and both 6teen and Total Drama Action switched time slots. On July 16, 2009, Stoked premiered, extending the block to 7:30pm. Later in 2009, Johnny Test returned to replace Stoked. In January 2010, the 7:30pm slot returned and the 9:30pm slot was removed. moving Johnny Test up to 7:30pm, returning back to its original timeslots from March 2008. On March 11, and 18, 2010, sneak peeks of Adventure Time aired and replaced Flapjack.

Har Har Tharsdays aired its final broadcast on April 1, 2010 and was replaced by a block called Monday Nights.
