I was starting to think, "He's not a patch on Senmaru" but then he got out the teapot & mouthstick!

The host refers to them as what sounds like, "The Moriahs" at the end which suggests an established double act, I couldn't find anything about them by searching for various Anglicised spellings. Running the video's description & comments through Google translate doesn't give me any more hints.
