Pulp Fiction is famous for the way the story is shown out of order.
If you have the DVD, you can program your DVD player to play the scenes in chronological order. The order is:
-
1
-
3 -> 5
-
22 -> 25
-
2
-
26
-
6 -> 21
-
27
That's not to say you should watch the film that way. It would probably break poor Mr Tarantino's heart if he knew you were doing that.
Thanks to posthumous for posting the chronology that helped me figure out the DVD scene order.
