"Kwarantined Krab" - SpongeBob SquarePants
This episode is titled "Kwarantined Krab." It was supposed to air in early 2020, but you can probably guess why it never went live. You can still find it online even though the Nickelodeon network never put it on air.
“Topless Showgirls” - Dance Moms
Dance Moms was already a super controversial show, but this dance routine really took the cake. The episode is titled "Topless Showgirls" so you already know that the network somehow thought that it was okay. Abby Lee had her dance team dress up as Vegas Showgirls and do a routine similar to that of a Showgirls. After it aired, it received a lot of complaints (naturally) and was taken off the network.
