I'm out on deployment with out my usual computer (ie, no photoshop :frown
Just wondering if someone could throw these together. I'm really not too picky, the only 2 things is that I would like it to be kinda dark/grungy and I would like it to say "Doc B". Thanks guys.

Heres what I've got. . .

Here's a couple more I found. . .
