Dude, use the word FUCK all you want. SC as a obscenity filter.
"F That"...that just kills a strip.
Also, dont rely so much on narration. There are rare examples of when a lenghty exposition works.
if your "story" is not simple enough to tell in three panels and a few lines of dialogue, then dont tell the story. Remember:
1st Panel ==> Introduction.
2nd Panel ==> Set Up
3rd Panel => Punch Line.
Also, go check out the strips of the Greatest SC Users.There's nothing wrong with a little imitation, at least at first.

There was once a man who said:"nothing is true!". Although later it was found out that he was lying.
