Irony: This is one of the few moments of the (uncut) movie more-or-less faithful to Quentin's original script. Doubly ironic when you realize that Quentin himself had only written this scene because the real-life bodybuilders on whom the Brothers are based had been interested in funding the film (long before Quentin had sold the script off), on the condition that they'd have a cameo...and that, therefore, Quentin wasn't particularly fond of the moment.
Wag the Director: Very little of this film is derived from Tarantino's screenplay. Tarantino says that the only aspect of the film he'll acknowledge as being his are the character names Mickey and Mallory.
As this Cracked article points out, had Tarantino directed and used his original script, the film could well have been a phenomenal success and, combined with Reservoir Dogs, launched his career years earlier. Michael Madsen has commented that, had Tarantino retained ownership of the project, he would likely have starred as Mickey.
However, someone managed to make a fanedit that attempts to revise Tarantino's original vision.
