Bill (David Carradine) shoots Beatrix (Uma Thurman) in the leg with a gun that shoots an arrow and says "Gotcha!". The same line and a gun with arrows is being used several times in the movie Gotcha! (1985).
Bryce Larkin and Chuck both say Gotcha! in the library. The first is when they are playing with with sucker dart guns and Bryce gets chuck in the head...and the second is when Chuck finds the CD
In "Gotcha!", the character Manolo says "Don't show me your badges, we don't know nothing about no stinking badges". This is a reference to "The Treasure of the Sierra Madre" where one of the Mexicans says "Badges? We ain't got no badges. We don't need no badges. I don't have to show you any stinking badges".
