Sports A Poppin' is the first part of the 21st episode in season 2 of Dexter's Laboratory, which first aired on December 3, 1997. In this episode, Dad tries to get Dexter to play sports, only for him to learn that Dexter isn't athletic.
Dexter's dad is inspired to teach Dexter how to play sports, despite many attempts he can't even teach Dexter to throw. He gives up and walks back to his chair, when Dee Dee shouts that she's let loose the giant monster, leading Dexter to spring into action, able to throw and jump easily.
