He is shown in a photograph with Mr. Burns given to Smithers. Smithers comments on how he was "so good to his mother", in which he was in real life until her death. The picture is a reference to the 1970 picture taken of him and President Nixon, which was kept as a secret at the time.
In Treehouse of Horror, his grave can be seen with the caption "Accept It". This is a reference to the conspiracy theorists who try and prove Elvis faked his death and is still alive.
He is seen in the Itchy and Scratchy cartoon Little Barbershop of Horrors.
In New Kids on the Blecch, he is seen in a photo as one of the people who joined the Navy. In real life, he was drafted into the Army and sent to Germany for 2 years.
