That's nice to hear. Start with Clerks
, but just so you know: the way Kevin designed and wrote the Askewniverse, Mallrats
(the second film) comes first in the continuity. The events in that movie take place a day or so before those in Clerks.
It's a long story that I wouldn't even begin to explain even if you wanted me to. Just watch the films and find out for yourself. Hope you like them.
