Stick around....wit and dry humor is hardly against the rules at TFL. In fact, there are only 4 reasons why Staff steps in: http://www.thefiringline.com/Misc/Policy.html
None of these include the commission of humor.
Yup, TFL tends to be more "serious" than other Boards. We also tend to be a bit more on topic, informative and better behaved. That happens to be our niche. Check out the Announcement on the new software....there's a feature there for private messaging which allows for uncensored comments at will. Clowns may not appreciate the feature, as they have an insatiable demand (birthright?) for public audience.
Such audience is available at a number of other sites.
Here's a site for great humor and uncensored comment: http://www.hardcoretalk.com.
