Instead, Ellen shows us how it's done in this comic.
Bob and George have made a running joke out of this with "Roll says the F word".
In fact, in the commentaries the author invokes the idea behind this trope, and only drops the F-Bomb (uncensored, at least) about once a year, in a dramatically appropriate context. Dave Anez abandoned this rule during the final year-and-a-half of the comic--which indicated/foreboded just how badly the crap was hitting the fan.
Throughout its over five-year run, Penny and Aggie has used swearwords sparingly, and has never printed them uncensored. (This was justified in its first two years, at any rate, when the creators were trying to get it syndicated.) However, in early 2010 there were two notable exceptions for dramatic purposes:
The bigoted, mentally disturbed Hubbard-follower Xena uses the N-word uncensored. (This results in her getting knocked unconscious in the very next strip.)
Social outcast Helen's bitter inner monologue, as she runs away, ends with the words "Fuck you, Penny. Fuck you, Belleville. Goodbye." Particularly unexpected as her monologue begins with the milder "Screw you."
A later example occurs when Sara, overwhelmed by the multiple stresses her reality show has placed on her, says "Shit" as she breaks down crying in Rich's arms.
In Homestuck many characters rarely swear, however, whenever a server player starts the game for the first time, the first thing they do is usually tear out their client player's toilet, and let loose an "oh fuck". Roseand Jade demonstrate.
