Broderick Brown is the younger brother of Cleveland Brown, and a co-worker of Dr. Hartman's at the Quahog Hospital. He appeared in "He's Too Sexy for His Fat". He also appeared in The Cleveland Show. Later on in both shows, his character seems to have been inexplicably written off and forgotten.
He appears in "He's Too Sexy for His Fat" when Peter Griffin talks to Cleveland about his son Chris Griffin's weight problem, and Cleveland suggests that they make an appointment with his brother. He's well known for his surgery on Nell Carter, who was twice as big before he performed on her. Broderick promises his technique is safe and doesn't hurt, describing it as sneaking through the bush and skulking around.
