Deleted Scene: James Bond and a villain are playing blackjack with Homer as the dealer. Homer gives Bond a joker. Bond tells him he has to take those away from the deck.

In the United States pageant, Lisa was Florida and Ralph was Idaho. They both won a trophy because Skinner thought that they clearly didn't get any help from their parents, but Homer worked on Lisa's costume, so Ralph alone, whose Idaho costume was really just a piece of paper on his shirt with Idaho written on it, should really get the trophy. Of course the joke was supposed to be Homer doing such a lousy job at making Lisa's costume it was comparable with Ralph's, which was just a shirt with "Idaho" on it.
In Bart's Casino, Milhouse had a magic trick involving putting a black cat into a box and it magically going into his magician's hat.

Homer parodies the scene in the 1939 film Wizard of Oz when Scarecrow demonstrates his newly acquired intelligence by reciting the law that governs the lengths of the sides of an isosceles triangle. Unlike in the film, somebody correctly points out that the Pythagorean theorem recited applies to right-angled triangles, not isosceles triangles, unless there is a right-angle in the triangle.
