From Wikipedia:
Tracey Takes On... is an HBO sketch comedy series starring actress-comedian Tracey Ullman. The show ran for four seasons, and won multiple awards. Each week, each episode would focus on, or "take on", a certain subject in which each installment would revolve. Unlike her FOX series where characters would frequently be one-offs, Ullman's new roster of characters (29 in all) would appear repeatedly for the duration of the series.
Ullman created and portrayed a wide spectrum of exotic characters for the show, including both men and women, young and old, of a variety of ethnic and cultural backgrounds, and sexual orientation. Six characters created for her previous two specials returned for the new series. Only her 'Kay' character would return from The Tracey Ullman Show.
In 1998, Ullman released a book based on the series, Tracey Takes On.
