My first experience with Syncro-vox was a spoof of it on The Simpsons. Had no idea what it was back when I first saw it. Then came Pulp Fiction and Robot Chicken and I still had no idea.
Now, thanks to Bob, I do. Also, I didn't know it was William and Joe who INVENTED Tom and Jerry, so therefore by association, a killer template for cartoon violence.
It's pretty amazing how a premise so simple (Why DOES he have a collar?) can have such a mind-blowing follow-through.
Also,on 4:49, is Top Cat hitting on Penelope Pitstop?!
