I read the other day that Nickelodeon had a 1-hour block every Sunday from 1-2pm EST called "Nick Rewind." It was a voter's pick thing, and there were no live action shows being shown. They were all Nicktoons, some of which haven't been aired in the last few years (they played Ren & Stimpy, Rocko's Modern Life, Aaah! Real Monsters, Hey Arnold, etc.). Along with the old Nicktoons, they also played the old station IDs, including one of the original "pinball" ones!! Someone caught it on tape and put it on YouTube. Here it is (and I haven't even seen it before): http://www.youtube.com/watch?v=RcprzesAyRk
I missed the whole thing. I wasn't even expecting that since last year was no anniversary for Nick. Weird.
