What to wear: Joyce has a more low-key '80s mom look than the rest of the parents on the show, so all you'll really need is a thin dark jacket, a striped shirt or chunky turtleneck sweater, and flared jeans with a shaggy brown bob hairstyle. If you really want to hammer home the fact you're dressing up as her, consider bringing a rubber axe or a piece of cardboard painted with the alphabet out with you. You could even go one step further and wrap part of your body in colorful Christmas lights.
How to act: Tense. Very, very tense. To really nail your portrayal of Joyce, walk around whatever Halloween party you're attending while yelling, "WILL!" and "Where's my boy?! Find my boy!" over and over again.
