Dolan and Weegee hate each other very much. In fact, Dolan hates Weegee even more than he hates Gooby, and Dolan hates Gooby a lot. The reason for the two's hatred of each other is because Dolan is the only creature to exceed Weegee's level of mental disturbance. This makes Weegee jealous. It makes him jelly, some might say.
