Lo, There Shall Come...a Bartman!!

Full Story
The Springfield Comic Convention is coming to town, and Arnold Leach, the man responsible for Radioactive Man, will receive the "Good Guy" award. Bart wants to go, but Marge reminds him (and Homer) that the semi-monthly visit to see Grampa is tomorrow. Initially, Bart is bored, but finds out Grampa has a near-mint copy of Radioactive Man #27, which was given by Grampa's neighbor, Morton Mankiewicz. It has a letter of complaint Grampa wrote, which was published on the fan mail page. Morton gave Grampa the comic book because of the complaint letter in it. Morton stops by to say hi, and shows Bart his comic book collection.
