|First appearance||Blowing Smoke|
Perry Demuth is the husband of Midge Daniels.
Perry and Midge are heroin addicts. Midge planned to run into Don at work and try to sell him some of her artwork. She told him to come with her to her home to meet her husband. When they arrived at her house, her Perry implied that Midge would have sex with him if he bought one of her paintings. He promised to make a great dinner, but has no cash on him. Don gave him 10 dollars, which he appeared disappointed in but left anyway. She told him that he would just put that in his arm. ("Blowing Smoke")
