What kind of nudity is there in this?

There's a warning about about
language & nudity before the show.

It's clear what the language is about
but i still haven't seen any nudity.

Is this a case where there's only nudity
in some of the episodes but the tv people
are too lazy to watch the shows so that's
why the warning is at the top of each shows?

(This happens alot at showcase & some
of the other movie channels).

If there's nudity,what kind is it?

is it only male butts?

The last time i watched, a woman
was lifting her shirt to show her
breasts but we didn't really see
anything.
