Dunno why, but reminds me of a joke of old (IOW, when I was not)(this old, I mean), about a bunch of inmates fleeing the asylum under the directions of a theatrical director. When they got to a safe distance, he yells "very good! I love you all! Great! Dress rehearsal was perfect - now let's all get back and be ready for limelight tomorrow night!"
