Sister Jean Delores Schmidt, the 99-year-old nun who stole the show at the Final Four, serves as a tour guide when hosts Jim Litke and Tim Dahlberg look back at the 2018 moments that warmed hearts, made us smile or get up and want to dance. There’s homecoming queens, rare displays of sportsmanship, random acts of kindness and a teddy-bear avalanche that will have you reaching for the Kleenex. On the menu: Chinese food for Christmas?
