After accidentally injuring him Monty Burns gives Homer eight weeks paid leave during which time he imagines himself taking amatory lessons from cool, white-suited fictional spy Stradivarius Cain, though, in addition to getting back with Marge, he also charms a drug baron's wife with near unfortunate results. To teach Nelson a lesson for stealing other pupils' lunch money Bart persuades him to eat nothing but Krusty-burgers, which render him obese and unhealthy.
