Few things annoy me more than when a writer dramatically builds up to a revelation or punchline that turns out to be already obvious. Here's an example from the Times this week:
In the drawing, a nude man and woman stand on either side of a wall. Each wears a plastic breathing mask that covers the nose and mouth; the masks are connected to air hoses that pass through the wall. The hoses attach to pouches at each other’s underarms and crotches. [OMG they're huffing each other's stank!]
It is a device that allows people — and there is no polite way to put this — [Whoa, what's he about to reveal that's even cruder than the fact that they're remotely huffing each other's stank?!] to sniff each other. Remotely.
