Interview with the Batman

In a rare coup, the Batman himself invited us into the Batcave for a tour and interview. He introduced us as well to "Johnny Whoa-Whoa," who, according to Batman, is a "brand new superhero" who even has his own theme song. Due to a camera malfunction Batman's performance of this song got cut off but for those who are curious, this is how it goes:

Johnny Whoa-Whoa, come out of the wall!
Johnny Whoa-Whoa, come out of the wall!
Johnny Whoa-Whoa, come out of the wall!
Johnny Whoa-Whoa, come out of the wall!
Johnny Whoa-Whoa, come out of the wall!

It goes on like this for some time, actually. And no, we have no idea what it means, either.
