The Simpsons get a zombie for a son-in-law in “Days of Future Future.” The story is set 30 years in the future. Milhouse finally gets Lisa to marry him but she spends all her time volunteering at a zombie soup kitchen, which serves vegetarian brains only. Her husband reluctantly visits her and immediately regrets it. A zombie accuses him of being racist for perpetuating the stereotype that all zombies have uncontrollable appetites for human flesh, then promptly bites Milhouse.
Fortunately, there’s a zombie cure but Lisa prefers zombie Milhouse.
“I even prefer the way he smells now,” Lisa tells Bart. “Some meat went bad in our freezer and my heart skipped a beat.”
Lisa eventually decides to give Milhouse the cure but a twist ending reveals that there was no zombie cure. It was a false memory belonging to Bart, who visits a Total Recall center to get over his ex-wife so that he hook up with everything from robots to aliens but thankfully no zombies.
