Jimmy Neutron: Boy Genius (partially found movie promotional TV shorts; 2001–2002)
When the Jimmy Neutron: Boy Genius movie was being released around 2001–02, Nickelodeon interrupted some of their shows with humorous shorts to promote the movie.
One such gag (supposedly) had the audio track on a Rugrats episode changed, another one giving the SpongeBob SquarePants cast hair in the style of Jimmy's, and another one that is confirmed to exist had a SpongeBob episode being made with puppets.
At the moment, no footage exists, due to it having been aired at random times. Only one (low quality) picture of the SpongeBob "puppet show" gag currently exists and was said to be taken from the Season 1 episode, "Hooky", until that episodes puppet interruption was found, leaving the episode the image was from unknown.
March 7, 2016 – Wiki member CDCB2 has an interruption during the SpongeBob episode "Employee of the Month" that displays Jimmy and Goddard playing fetch with the Nick "network bug". CDCB2 says he'll upload it once he finds the disc.
Next, a lot of sightings have been claimed. An anonymous person claims that during the Rugrats episode "Music", he gave the Rugrats cast his hairstyle much like the SpongeBob one above. Another anonymous person claims that during the Hey Arnold! episode "Helga Sleepwalks", Jimmy replayed a scene of Helga eating pork rinds a few times. Another anonymous person claims "Squeaky Boots" getting the "puppet show" treatment, and yet another anonymous person claims that SpongeBob episode "Culture Shock" received not one, but two interruptions. The first one was where Squidward talks to the group behind the curtains. The anonymous user says that supposedly, he was given Jimmy's hairstyle. The second one was that the colors supposedly inverted for a few seconds. The same anonymous user claims that during another episode, a part of the episode repeated a few times, much like the "Helga Sleepwalks" situation above.

January 11, 2017 - More interruptions have been claimed to exist. First, there was one on the Rugrats episode "Reptar 2010" where he, like similar interruptions mentioned above, replaced about a minute of the episode with Rocket Power (coincidentally, Rugrats and the two shows that he briefly replaced portions of certain episodes with, Rocket Power and The Wild Thornberries, were all Klasky-Cuspo productions). Another that now has been claimed to exist was in the SpongeBob episode "SB-129" where he gave Squidward Carl's hairstyle and glasses and even went as to far as to give Squidward Carl's voice. Yet another claimed to exist was one during an episode of As Told By Ginger where the colors were briefly inverted much like the "Culture Shock" interruption above. Finally, a video of yet another SpongeBob interruption was posted by the Youtube account Final Atomic Buster and has been added to the video gallery below.
March 20, 2017 - Another interruption was discovered, courtesy of YouTube user The Tide and Seeker (Tide on the Wiki), on the SpongeBob episode "Ripped Pants". In it, Jimmy and Goodard fly in on a rocket during the surfing competition. The first rewind was in the episode to the point where SpongeBob and Sandy Cheeks are buying ice cream, but it is in slow motion. The episode is then fast forwarded to the point where SpongeBob rips his pants through a box. Finally, the episode is fast forwarded to the lifeguard picking up SpongeBob's (thought to be) dead body, which would have occurred right after where the interruption began, skipping the part of the lifeguard running to SpongeBob.
