I watched RAB a long, long time ago and am rewatching it out of nostalgia. Let's talk easter eggs.
The start of the flash movie intends for you to watch channels 0-9, where 9 takes you to the actual episode, but the channels go all the way up to 999.
Autism goes hard, so I browsed all 1000 channels and found easter eggs on several of them. All other channels randomly select from one of six placeholders at the time they're switched to:
* TV static
* annoying noise system
* broadcast test screen with tone
* boob girl
* we are experiencing technical difficulties
* please stand by
The easter eggs are on channels 999, 666, 500, 123, 111, 100, 69, 50, and 10 (I don't consider 0-9 to be easter eggs since the UI literally tells you to browse the single digits). I did click through very rapidly so I could have missed some. Accessing any channel that starts with a 1 is problematic because sometimes the UI will break in such a way that it instantly loads channel 1 once you press 1, so AFAIK the only reasonable way to get to channels 123, 111, and 100 when that happens is to type 99 on the remote and then channel-up to them. To get to channel 10, type 20 and channel down to it, because channel 9 loads the episode and locks you out of the TV. You can also try closing and reopening the flash movie.
I did not sit through channel 4 for an hour to see whether something happens or it's an infinite beer sipping loop. Someone else can do that.
