Jay and Silent Bob Strike Back/WMG

The entire movie is in Jay's head.

 * After the arrest mentioned Clerks II, Jay is going through detox and hallucinating the whole thing. This is why nobody in Clerks II mentions his imaginary girlfriend.
 * But without the movie money, how did he and Silent Bob fund Dante and Randal buying the Quickstop?
 * Plus the shirt (or hoodie, whichever) near the end - Justice TLF.
