Either Bob is cheating (somehow) or he is a very good poker player.
NOTE - I don't play poker so I had to look up the hands, I don't really know the rules so yeah.
In this comic Jeff was originally Jack, but I thought that Jeff would fit the part better. Because of this his hands seem a bit claw-like.
Also for the sake of expressions in my comics Jeff will be able to squint or do other expressions with his eyes, despite him not having eyelids. Also his cut mouth, despite being carved into his skin, will be able to change shape slightly for the sake of expressions.
Also sorry this took so long, I've been sick and not in the mood, but I do want to make people happy so I will try my best to keep at it.
I know Bob is not as famous a creepypasta monster as Jeff the killer or Slenderman, so if you don't know him here's his profile thing - [link]
(sorry I don't know how to link the actual pic, so just scroll down till you see his entry) and Bob's story (or at least the sequel I think) [link]
realistically I think Bob would have more human shaped teeth, but I think he looks better with sharp shark-like teeth
