Debunking Black/Color Bars, Spongebob Confirmed FAKE!!! Real video found.
From The Lost Media Wiki
Here's the reasons why Color Bars is fake:
1. the nick japan logo is still there, even when the channel shuts down. 2. the color bars slowly fade in, which is not usual. 3. that's not even the final bumper for the channel before it shutdown.
The Spongebob one was confirmed fake but I don't know why it is.
Anyways, here's the real one: https://www.youtube.com/watch?v=PHiakisQBqw&t=124s&ab_channel=%7Binsertchannelnamehere%7D
