Things RP talks about, among many more: his visit to Africa and deciding never to use the "n" word again, his addiction to crack cocaine, the burning of his body and the initial treatment.
He mimics well many kinds of people, which is impressive. His fake Italian ranks up there with Sid Caesar's fake languages in my book.
Per his IMDb bio, RP was diagnosed with MS in '86, died in '05 at age 65, and has acting credit into the late 90s.
