The opening titles consist of the following:
- Various colored backgrounds.
- Spinning concentric orange circles.
- A black limousine that drives across the screen several times.
- A theme song that consists of the accented female singers barking the shows title — "Big O! Big O! Big O! Big O!" — followed by bass synth.
- Robots, I think.
- And a section where the four main characters are introduced. We see a picture of their face, plus their job. The jobs are as follows: Negotiator, Officer, Android, Butler.
But don't watch any more than that. Because your brain would melt.
By the way, a better four-job set-up than Negotiator-Officer-Android-Butler, I think, would be Trombonist-Gourmand-Toddler-Crosswalk Guard. See? Brain melting.
