oh yeah Clerks is highly recommended! if u thk it is good then u should consider checking out the following too: Mallrats, Chasin Amy, Dogma, Jay And Silent Bob Strike Back and Clerks 2. Chasin Amy is more of a romantic comedy and Clerks 2 is my fave!
a word of warning: contain explicit dialogues(all), sensitive issues like racism(nearly all) & religion(dogma) and "inter-species erotica"

(clerks2).
