Great Episode,four stories

500 keys is a great episode with a great storyline and two great side stories,there is usually only two stories but in this one we got four which I found great.

When Marge shows the family a box full of keys she and Homer found but never returned,so she gives a set of them to herself,Lisa,Bart and Homer separately.One of Lisas keys are a key to a unknown room in Springfield Elementary,which leads to a secret room no pupils ever knew about.Meanwhile,Bart has other plans and uses the keys for his own entertainment,which only leads to him doing good deeds.Meanwhile,one of Homers keys opens to the Duff Brewery and goes on the Duff Blimp (which Homer wanted to go on since Season 4s Lisa The Beauty Queen)and takes it around Springfield,but doesn't wanna get out,and finally one of Marges keys turn out to be a missing piece from a farting toy Homer got Marge for there anniversary,and the thing moves around farting all the way around town and Marge and Homer try to retrieve it.
