The Cubs paid it forward on Friday by sending the Houston Astros at least 40 pizzas in honor of their World Series win.
It became a tradition in 2014 when the Boston Red Sox, who won the World Series in 2013, sent hometown pizza to the San Francisco Giants front office after their championship.
The Cubs kept that tradition alive by sending pizzas from Fuzzy's.
Last year, the Kansas City Royals sent the Cubs pizzas from Giordano's.
Will the Astros be sending pizza back to the Windy City at this time next year?
