Trivia question for the Wire affecionados

In which episode of The Wire does the longest "Sheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeet", as articulated by everyone's favorite corrupt politician, Clay Davis, occur?

I'm thinking that one episode in Season 2 where Daniels and Davis have a confrontation. But the current season, what with Davis' indictment and all, might be well posed to beat that record.
