Depressed by his humdrum existence Homer gets in touch with Eduardo, his childhood pen-pal, who comes over from Barcelona to help him live out some of his childhood wishes, such as driving a fire engine and gliding. At the same time Lisa devises a plan to stop cheating in the school by getting the pupils to sign a pledge. When she catches Bart cheating she wants him to own up but he will only agree if he gets a sign from above - which he gets in the shape of free-falling Homer.
