I don't know if this approaches Brechtian technique or not, but ...
When MOONLIGHTING was in its ascendancy, one of its victims was the
crime drama, RIPTIDE, about 3 private investigators. RIPTIDE ran an epi-
sode titled "If you can't beat em," in which the PIs are hired as technical
consultants to a tv show that was an obvious parody of MOONLIGHTING. In
the course of the episode, the Riptide PIs take the actors from the show on
a case, and point out the types of errors TV PIs make (like convoluted ded-
uctions on virtually no evidence)--and after they point out each error, the
regulars look at each other and clips from previous RIPTIDE episodes show
them doing the same thing.
