Chief Al Connor is Pawnee's longest-tenured department head, having taken over the Fire Department at age twenty-nine, after everyone else quit due to lack of hoses. He is known for his easygoing manner and corny jokes, as well as for having that disease where you can't feel pain when exposed to extreme temperatures. So, "firefighter" was kind of a no-brainer, career choice-wise.
For the Pawnee Mural contest, he and his team created a 'camel' of dogs playing poker with an 'everything on fire theme'. It also had some 'other things they liked' on it, including women. Their mural inspired Leslie to use her own team's camel. His mural did not win the contest, nor did any of the others, as an older mural was restored.
