The World of Tomorrow - Since Binky's repeating third grade, he's totally dreading Mr. Ratburn's annual class sleepover at the Science Museum. After all, he remembers how boring it was last year... wouldn't the second time around be twice as dull? But an enticing new exhibit - on visions of the future! - shows Binky that science knowledge can really come in handy. Is There a Doctor in the House? - Arthur and D.W. face the ultimate challenge when Mom gets a bad cold and then... (gulp!)... gives it to Dad! What if Arthur has to take over Dad's catering business? And how will they raise Baby Kate all by themselves?
