 Joe was an Eastside drug lord who preferred a peaceful solution to business disputes when possible.
 He was responsible for creating the lucrative New Day Co-Op with Stringer Bell, supplying much of Baltimore with heroin brought into the city by "The Greeks".
 Joe was a portly and amiable presence, but was often a match in wits for rival drug lords Avon Barksdale and Marlo Stanfield, and was able to manipulate most situations to his advantage.
 His nickname stemmed from his trademark phrase "I've got a proposition for you", going back to his days selling test answers on the school yard.
 Along with Poot Carr, Wee-Bey Brice, Omar Little, and Bubbles, he is one of the few characters from the drug trade to appear in every season.

 Wee-Bey is serving consecutive life sentences for multiple homicides committed on behalf of the Barksdales, having even confessed to crimes he did not commit.
 Grateful because Wee-Bey shielded the rest of the organization by taking the prison sentence on himself, the Barksdales provide for Namond and De'Londa.
 Even after the organization is shattered by the incarceration of Avon Barksdale, his sister Brianna Barksdale continues to pay them.
 This steady income means that Namond is much better off than his peers.

 He frequently orders the deaths of those who disrespect him or undermine his name on the streets, however unwittingly.
 He is arguably the most violent and ruthless of the drug kingpins portrayed in "The Wire"; In 2016, "Rolling Stone" ranked him #2 of their "40 Greatest TV Villains of All Time".
