Only Sane Man: Only when compared to Garth and Dean, of course, but Rivers seems to be the only person involved in the production that realized what it was awful, but is too polite to mention it.
Really Gets Around: Implied in the last episode when it's stated that the broccoli infection is sexually transmittable. Also and Informed Attribute as Sanchez is never seen with any other woman apart from the broccoli infection victim and is constantly being shot down by Liz.
The Sociopath: Learner in real life is strongly implied to be a serial killer.
Soul Brotha: Thornton Reed is probably intended by Marenghi to be played as a Soul Brotha; he says in the first episode that if Dagless doesn't pull through, "My ass is grass! And he (Won Ton)'s got a lawn mower, ya dig?". Dean Learner cannot quite pull this off.
