When Carl Met George/D.W. Swims with the Fishes

S13 E11: When Carl Met George: George is excited about spending time with his new friend, Carl, who seems to know all kind of cool facts about trains and about… well lots of things! Then George learns that Carl has Asperger's Syndrome - a form of autism that makes Carl see the world differently than most people. Can George and Carl remain good friends - and perhaps even learn from each other? DW Swims with the Fishes: D.W. and James enter the pre-school swim meet and recruit their big siblings to coach them. All goes swimmingly until Arthur and Molly start taking their jobs a little too seriously. Who's this race about, anyway?
