This week, Allie and Julia swing by singer-songwriter Mac DeMarco's home to learn about his love of "The Simpsons." They'll chat about "Lisa the Greek" – in the episode Lisa tries to bond over sports with Homer. Meanwhile, Homer secretly uses Lisa's ability to pick winning football teams to help him gamble. Mac will tell us why he always wanted to be as cool as Bart, and why he related to Lisa. Plus, he'll tells us about some of his Simpsons memorabilia, and why the saxophone is the perfect instrument for Lisa.
