A fun basic episode... I liked the sort of mystery component to Lisa and Bart's story; though I figured Martin was not actually dead, it gave a good opportunity to see how they dealt with the guilt, and I especially liked Lisa's reactions. The "Sneakers" thing was sort of fun (Homer's last moment with the bell pepper was quite amusing), but got a little standard by the end. Anyway, that's it - probably most of this stuff is already said by now.
DYN: ...the Happy Little Elves are back (though as part of Captain Kiddy's Comfort Carnival)? ...Homer talks about ensuring conservation of mass, even though he works at a nuclear power plant (where mass is converted into energy)? ...Russi Taylor is still just an "Also Starring"? (Compare 8F22, 4F06) ...a suspicious absence of Milhouse?
