Channel Hop: Nick finally takes advantage of their legal right to show pre-sale-to-Disney episodes of Doug.
While Nick has the airing rights to the whole Power Rangers franchise, most people probably weren't expecting Mighty Morphin' Power Rangers to air in any capacity on the block. It ended up airing as part of the "Mighty Morphin' Weekend" event to celebrate the 20th anniversary of the show. No clue if it'll return along with the rest of the 90s Power Ranger series.
Edited for Syndication: One of the drawbacks of airing 1990s reruns of kids' shows 20-odd years later. TeenNick cut out the musical performances from All That due to music licensing issues, and Rocko's Modern Life is still shown edited since Nickelodeon lost the original masters at some point. (Similarly, these versions are also on the Rocko DVDs.)
