I'm standing in line at the salad bar tonight, behind two birds in their mid 20's. On of them has an ass that you could land VTOL aircraft on and she is attacking the potato salad like the Marines at Mt. Suribachi. Long story short, the fat one is jabbering about how she can't loose any weight. What is the proper response in this situation? I know what it isn't. "Try laying off the potato salad, Bertha." Some people have no sense of humor. End of lesson.
