"Lessons" is the eighth episode of the first season of the HBO original series The Wire. The episode was written by David Simon from a story by David Simon and Ed Burns and was directed by Gloria Muzio. It originally aired on July 21, 2002.

As Wallace helps one of his young charges with their math homework, Poot shows up and asks him to return to work. Wallace refuses to leave his room and asks to borrow money from Poot, who begrudgingly obliges. Afterward, Poot reports his concerns about Wallace's to D'Angelo, who wants to talk with him face-to-face. Meanwhile, at the Barksdale-run print shop, Stringer scolds the staff for not acting like professionals. Wee-Bey, Stinkum and Savino raid Omar's apartment and torch his van while he watches from his hiding place across the street. Later, they pick up D'Angelo, who mentions Orlando's proposition; the others tell him that he should talk to Avon. Orlando is berated and beaten by Avon for even considering getting involved in dealing.

The soldiers throw a party celebrating Stinkum's promotion, which will be official as soon as they kill a dealer named Scar and chase his crew off his corner. D'Angelo goes out for more alcohol. When he returns, he realizes that a dancer Keisha has died during the party. Wee-Bey seems unconcerned, but D'Angelo is slightly shaken. Later, Shardene asks D’Angelo about Keisha, and he tells her that she was sick when he last saw her. They discuss his future and she tells him that if he is unhappy, he should do something else. As Wee-Bey and Stinkum prepare to hit Scar's corner, they are ambushed by Omar; Stinkum is killed while Wee-Bey is wounded. Avon increases the bounty on Omar, but Stringer suggests luring him into the open with the promise of a truce.
