Trivia: You can hear the Wilhelm scream twice during the scenes in the restaurant. The first comes just after the Bride fights Johnny Mo after the screen turns black and white. The second comes when the Bride races up the banister (during the "Nobody But Me" song). She slices a guy, then shoves him and he rolls backwards down the stairs.
Trivia: When the bride has the sword through one of the '88's", and is somewhat "dancing" with him, turning in circles, whilst the others are moving out of her way - the music being played is the same music from the movie "Gator" with Burt Reynolds, during the climatic scene at the end at the motel.
Chosen answer: Tarantino has said that he intends Kill Bill to exist in a slightly different world than the real one. In this world weapons are more commonplace and can be freely carried. If you notice, on the plane there are actually little holders on all the seats for people to put their swords into.
