My pick would be It's a Mad, Mad, Mad, Mad World.
A dying crook tells a disparate group of people where they can get their hands on a huge pile of loot. Crazy with greed, they lie, cheat, steal, kick, punch, eye-gouge, and try to run each other off the road in a frantic effort to get to the hidden stash before everybody else. They fail disastrously to achieve their goal, and many of them end up in traction in hospital, facing serious jail time.
Not only does that sum up life on earth but online marketing as a whole. I mean, my synopsis reads like a WSO and its aftermath. Am I right?
