Kill Bill: Vol. 2 (2004)
At the end of Pulp Fiction, Jules says he wants to "Become a drifter, and walk the earth." In Kill Bill Vol. 2, Rufus at one point says "I was a drifter..." while telling his story in the church.
However, there is no proof to this theory because when Rufus says "I was a drifter," he also says "I was a Coaster, and I was a Temptation. If they came through Texas, I played with them," inferring that he played back up for the bands The Drifters, The Coasters, and The Temptations."
Whether or not Rufus is actually Jules Winfield telling tall tales, only the filmmakers know for sure.
