In Young Sheldon season 3, episode 10, “Teenager Soup and a Little Ball of Fib,” Sheldon claimed he was ill so he could avoid swimming in a school pool. Sheldon was horrified by the thought of taking a dip in water that was shared by dozens of other swimmers, resulting in a surreal nightmare sequence where sentient pool water spoke to him.

The pool tried to convince Sheldon to take a swim, telling him that it wasn’t as gross as he feared. Hilariously, Young Sheldon’s talking pool was voiced by The Big Bang Theory star Kaley Cuoco, who played Sheldon’s neighbor, nemesis, and eventual dear friend Penny. Like the talking pool, Penny was always trying to convince Sheldon to lighten up and try new things.
