I've noticed there's a distinct lack of "sense of humor" here at times, especially when a politically correct topic comes up. Personally, I enjoy a good joke... and most often, I enjoy the bad ones, too! I don't think there's anything unprofessional or unbecoming of finding some humor in the world.
We all create what's around us; good, bad, boring, exciting, funny, not funny. We're all fodder for the comedy caravan, in my opinion. A world without laughter would be a dreary place indeed... and not all that is funny is Rated G.
