When Homer and Bart visited the steel mill (as part of Homer's effort to make sure that Bart was straight), Roscoe told them that the workers worked hard and played hard. Roscoe then pulled a chain which made music play and a disco ball come down from the ceiling, and the workers (who were all gay) started dancing with each other. Homer then ran away from the mill, taking Bart with him.
Trivia
At the 3rd of June, 2015, Roscoe was added to The Simpsons: Tapped Out as a part of the "Pride Month 2015 Update".
