They did have a falling out, but I don’t think exactly what happened is clear. It was brought up on the roundtable episode they had a few weeks back. Mark and Jeff just said they weren’t happy with Jim Tom and they probably wouldn’t be working with him again.
I saw that and said, Hummmm wonder what happened?
And then I thouht to myself, Mark did get pulled over! Jim Tom was a talker, maybe talked too much about show?
