Happy Anniversary

Happy Anniversary is both part a and b of the first episode, being around 23 minutes long, of Season 10. It first aired on May 15, 2006.

Summary
It is Arthur's parents' 10th anniversary and for their special dinner, they're going to a special restaurant but Arthur needs to go to Buster's house to sleepover, write a report about perspective and watch the Bionic Bunny 10th Anniversary Special while D.W. needs to look for tin. All gets worse when Grandpa Dave needs to go to the Fireman's Ball and the car is stuck in the middle of the road. The entire Read family comes to understand that spending time together is indeed the most valuable celebration of all.

Plot
Mr. Ratburn shows a film about perspective and then assigns the class an essay about it. Arthur and Buster are disappointed to have homework on the weekend of the big Bionic Bunny / Dark Bunny special (in which everything will be revealed), but vow to complete it before the start of the special. Arthur, however, struggles with the assignment. Mr. and Mrs. Read are celebrating their tenth anniversary at a fancy restaurant. They're dropping Arthur off for Buster's sleepover and D.W. at Grandma Thora's. But car troubles leave everyone stranded. Things seemingly go from bad to worse when Arthur and D.W. get locked in a storage room in an old diner. They're disappointed, and a bit scared, but find inspiration in an old radio drama called "Kid Carter and his Sidekick Mistral."
