Huge plot mistake
All the three stooges take part of the "Jersey Shore"'s audition. The Old Spice (OS) guy hires Moe only and conviniently "pretends" that there was nobody else on the stage besides Moe by commenting on the Moe's stage performance only.
Later Larry and Curly visit Moe at the "Jersey Shore"'s filming location and the OS guy says surprisingly "Are you kidding me? There's three of them?" as he "pretends" that he sees them for the very first time. The fact that there are not one, but three stooges, inspires the OS guy to think up a new reality show and to pay the orphanage's debt which is the great goal of the stooges.
From the "Jersey Shore"'s audition scene onward the movie's script should be reworked which is more than a third of the movie's runtime.
PS: I liked very much the acting of the three main actors.
