“I hate reference humor,” Annie moaned as she wandered helplessly through the “haunted” Hawthorne mansion in last week’s Halloween-themed episode of Community. The ingénue clearly hasn’t been paying attention to her last three years at Greendale, where a quest to garner the coveted chicken fingers in the school cafeteria affectionately sent up The Godfather and Goodfellas. Or where a study group could spend an afternoon trapped inside a runaway Kentucky Fried Chicken spaceship. Or where a simple birthday party might wind up with an elaborate Pulp Fiction theme. (Annie was Honey Bunny.)
