1. skinner
I just think he's the funniest dude on the show. But he also loves his job! His relationships with Chalmers AND his mom are always hilarious (his mom is secretly one of the funniest people on the show). And his love/hate relationship with Bart is classic. Also is the best member of the Be-Sharps. Just rules rules rules.
