Throw It In: When the Hulk first fought the Fantastic Four, Stan Lee famously goofed and referred to Banner as Bob Banner throughout the issue. That's why, from then on, Banner's full name has been Dr. Robert Bruce Banner.
According to this source, Peter David originally intended for the Hulk's temporary girlfriend Marlo Chandler to be a prostitute like her roommate who helps set her up with the Hulk. This was during the time he had adopted the persona of Joe Fixit and was working as a mob enforcer in Las Vegas. However he was told he couldn't do that and so changed Marlo into an aerobics instructor and her roommate a nurse, though when reading the comic it is clear that there is little explanation why a nurse would be associated with a mob boss and said mob boss would think an aerobics instructor would be the best choice to spend time with Fixit.
