After his fantastic performance, Elvis introduces his twin brother Melvin who is really Milton Berle dressed up like Elvis complete with fake skinny legs. When Milton appears he's a riot with his funny dialogue, fun personality, and humorously keeps promoting Elvis. Even Elvis seems to be enjoying Milton's performance while also staying cool. He even accidentally calls him Milton by mistake as Milton then immediately makes fun of the slip up. On top of it when Elvis plays "Blue Suded Shoes" again, Milton joins in dancing like Elvis and breaking his guitar, however, with all this happening, Elvis still remains as the focus during the skit.
That was Elvis' first performance on Milton Berle before his controversial "Hound Dog" performance on the show. Despite one error, Elvis is still rockin and Milton is a riot.
