So an American girl and three Chinese guys sit down for hamburgers...
And continues with:
...and one of the guys offers to pick up buns without knowing what they are, so the girl sends him a jpg file.
And moves on to:
...and another guy cracks pepper over just one portion of the patty, which makes it resemble a used ashtray.
And adds:
...and one of the three creates an unevenly pressed patty which could double as a UFO or a football for players with impossibly small hands.
...while another nervously flips the sizzling masses in the pan, miscalculating his landing by enough to evoke scenes of Vancouver Olympic bobsleds gripping the icy walls of sharp turns.
And concludes by saying:
...but the didactic undertones of hamburger night make it more than just a meal with friends. They learn to create; pressing and forming shapes, grinding pepper and exercising patience in letting the meat cook undisturbed.
...and they become kitchen jesters whose only collective goal is to somehow fit stacked tiers of food into one comprehensive bite, each angle of attack proving as unsuccessful as the first.
...and their satisfaction made evident by the first quiet mouthfuls of their very own burgers of labor.
So maybe it's a joke only by definition of our laughter within the evening.
