Yeah and probably best as that is what Bob Odenkirk (Saul) is best at- smart mouth, really cold observational comedy and delivery.
As to B.B., I always thought at least half of that show was a black comedy anyway. I always thought a lot of people watching were laughing or at least smirking a bit at some of the darkest parts of that show- the tub, the guy and the acid all landing in the hallway followed by Walter chastising Jesse (yet again) about WHY he told him to get a polyethylene tub was sort of funny, at least in a sick, twisted way.
And then the direct humor: 'Good morning Mr. Salamanca... do you have to go poopy? Did you already go poopy?' At the end of that episode of course, Mr. Salamanca blows the 'poopy' out of the entire nursing home....

Its been said that BB was more drama than comedy and Saul will be the opposite.
