My personal definition of Halloween has evolved somewhat throughout the years. In the early days it meant venturing outside in a homemade cow costume complete with udders and soliciting strangers for candy on a freezing Michigan night. In college, it meant wearing badly constructed outfits with “sexy” in the description (nurse, referee, cowgirl, etc.) and paying bartenders for beer on a freezing Michigan night. These days I shop for therapists to talk to after my inevitable loss to someone more creative than I in the office Halloween costume contest. Still, there are a few spooky essentials that have managed to transcend the cruel process of aging: crappy pink bubblegum, pumpkins, and The Simpsons: Treehouse of Horror. I have a particular fondness for scenarios involving Homer and a donut. Here are ten clips from some of my favorite episodes throughout the years:
