GoOFs
In the Goofs section, it mentions about Lapointe talking about his "Double double, with eight sugars" .
More than likely, this was a bit of wacky dialogue rather than a goof.
In the audio commentary, Kevin Smith mentions about a flashback scene where you can see the edge of the pool when it was supposed to take place in the ocean.
Kevin left it in there intentionally.
Another mistake not mentioned in the Goofs section was the scene when going trough customs.
The scene starts out with a bunch of people/extras going through customs,
then cuts to Wallace and the border agent who appear to be alone.
