Jules Myrick is a cartoonist for the action strip Wings Wagner.
Scooby Doo... Where Are You! (Gold Key Comics)
He was good at thinking up predicaments for his hero, but no so good at figuring ways out of them. He set a series of traps for the gang to see how they would solve them, always with a way out under his control, just in case they failed.
In the end, the gang forgave him and even helped him with his comic strip, coaching him with some new ideas.
