When commuting to work one day, I had the idea that a subway tunnel is like a cave. A Bat Cave. Something Matty would love. He’s a Bat Afterall.
And after a while Matty would comically go the wrong way and possibly into a subway train. While hurting oneself is not particularly funny, it is to a cartoon character. Like something the old Looney Tunes characters would do. And Matty would fit that bill.
Slamtown Express. I have a way with words.
