Watch Jon Hamm Defend St. Louis Pizza on Jimmy Kimmel Live

Mad Men star Jon Hamm was on Jimmy Kimmel Live earlier this week, where he and host Jimmy Kimmel did a pizza taste test. Kimmel tells Hamm (a St. Louis native) that he finds the beloved St. Louis pizzeria Imo's "terrible." To prove it, Kimmel asks Hamm try a pie from Imo's ordered to the Los Angeles studio from St. Louis versus Kimmel's own homemade pie. (Kimmel actually has a pizza oven at home that he built with the guidance of master pizzaiolo Chris Bianco.) While Kimmel's pizza admittedly looks awesome, Hamm sticks up for his hometown's square slice: "You can taste the Gateway Arch ... It tastes like 11 World Series victories." But Kimmel's pie doesn't cut it. "Jimmy, this is delicious pie," says Hamm. "But I'm going again with Imo's." The pizza action starts around 1:45. Go, watch:
