#2 Kevin Smith actually based the main character Dante after himself. Randall was written almost completely based off of Smith's long time friend Bryan Johnson. You can see a "real life" Randall on the reality show Comic Book Men, where said Bryan Johnson is 1of4 main cast members that run Kevin Smiths personal comic book store, Jay and Silent Bob's Secret Stash. (Notice I said "run" not "work". These are the real life Clerks in their natural habitat.)
It's a fun show that has not only Kevin Smith in every episode, but the egg-obsessed guy shown in #19, Walt Flannigan!
