As he struggles to be understood by his family, classmates and neighbors, his mother arms him with the best tool she can come up with: reminding bullies his dad is the football coach and his brother is on the team. His twin sister doesn’t share his exceptional mind, but she has a much clearer vision of what life has in store for the young genius. About TBS: The home of Friends, Young Sheldon...
