In science, a black swan relates to an event that is impossible to predict because it exists outside the realm of normal expectations.
Within the off-kilter world of "Curb Your Enthusiasm," most of the consequences of Larry David's actions could be considered black swans, but never with the literal-mindedness of this week's episode, which found Larry committing involuntary manslaughter, voluntary cellphone abuse, misunderstood additional gratuities, and defensive homicide upon a prized swan with a golf club.
Unfolding with the tension of an Agatha Christie murder mystery, this week's episode focused on the catastrophic fallout from various decisions that Larry made, whether that be a benevolent gesture that goes awry or the wanton killing of a rare bird.
The Additional Gratuity. Judging from the amount of time that tipping has come up over the course of seven seasons of "Curb," it's a contentious subject to Larry David, whether it be overtipping, coordinating the tip, tipping the dining room captain, or the vagaries of the additional tip. Personally, I've never understood the concept of the additional tip, which is often confusing and misleading. In this case, Larry had already paid a mandatory 18 percent tip, so the addition of a further tip seems superfluous at best. (As for the waiter's explanations of how to calculate a 2 percent tip, he should really head back to high school math class, despite Larry's promise to protest math at the table.) I'm siding with Larry on this one. Yes, amazing service should be rewarded, but a waiter demanding an extra tip on top of the mandatory one is a little much. (As for Larry giving the waiter a $500 tip because he mistakenly believed he was being blackmailed? Chalk that one up to miscommunication.) Larry: 1. Humanity: 0.
