We Christians should be able to have a good laugh at our own quirky tendencies; shucks, we put the "fun" in "fundamentalism." The main problem lies in the fact that Hollywood's writers, producers, and actors do not take the time to get to know us well enough before they portray us and, therefore, parody Christians based on preconceived notions.
"GCB" is a much less clever spin on Jonathan Acuff's Stuff Christians Like, which is regularly read in CWA staff meetings. And "Things Christian Girls Say" spread through my office like wildfire. Because, after all, we do innately think we should be journaling more (and be careful where you place your hand during that side hug).
The fact that ABC took time to point out Christians' common idiosyncrasies could be funny.
