When Hank gets a new co-worker at work- Tammy. Peggy helps her to get her quilification, Tammy is then invited to stay at the Hill house. It then turns out she is going out on dates but is selctive as no one seems to last for more than 1 hour. Evantually Hank unknowningly becomes a pimp. Then one of Tammy's former pimps comes to the neighbourhood and wants Tammy back. In the chase Hank squares up to him and he flees.
In my opinion this is one of the best ever King of the hill episodes. It is one again where Hank and Peggy are lured into something they didn't know was happening. Comic Genius.
