Bob Simms, played by John Michael Graham, is a character in the 1978 film Halloween.
Bob is the boyfriend of Lynda Van Der Klok. After having sex with Lynda in the Wallace house, she asks him to go get her a beer and he does so. When he is in the kitchen, he hears a strange sound and thinks it is either Lynda, Annie Brackett, or Paul playing a joke on him. However, when he opens a closet door, Michael Myers jumps out and pins Bob to another door by stabbing him in the stomach.
His scenes in the reboot are similar to the original's, although they happen in the old Myers house. In the 2007 film he is portrayed by Nick Mennell. In the uncut version of the 2007 film, Bob is stabbed to death by Michael as he attempts to get beer from his car.
