In the clip show "Picks of the Litter" Homer's last name was revealed to be Vincent.
One of three times Wishbone did not tell a story (Homer told the story of Anansi and "When People Could Fly" - though Wishbone did conjure up a few images of Anazi to explain who he was first). This was also the only time, excluding the clip show "Picks of the Litter", where more than one story was told.
