 Why is it ironic that the narrator's wife is asking him to be quiet during the broadcast?
The only kind of gag worth pulling, I always maintained, was a cosmic one—till I learned the Cosmos has a really nasty sense of humor! I heard my daughter's running feet in the animal rooms and her rollerskates banging at her side. Yet I had always been so sure I could create them that I had been calling them volplas for ten years. I had called them volplas since the day old Nijinsky's elongated arms and his cousin's lateral skin folds had given me the idea of a flying mutant. "Tell your mother that I retaliate. Again in the laboratory, I entered the metabolic accelerator and withdrew the intravenous needles from my first volplas. The accelerator had forced them almost to adulthood in less than a month. It would be several hours before they would begin to move, to learn to feed and play, perhaps to learn to fly. Meanwhile, it was clear that here was no war of dominant mutations. My wife tried the door, too, but more subtly, as if casually touching the knob while calling. I flipped a hamburger and a slice of onion onto a plate and picked up the ketchup and said, "I've reached the dangerous age." I wiped the back of my hand across my mouth and said aloud, "Yes, sir, the dangerous age. I kissed her until I heard rollerskates coming across the terrace from one direction and a horse galloping toward the terrace from the other direction. The spars had been common to the basic colony for years and were the result of serial mutations effecting those greatly elongated fifth fingers that had first appeared in Nijinsky. Suddenly, as I teased the male volpla, this happened. As they swept out and forward, the lateral skin that had, till now, hung in resting folds was tightened in a golden plane that stretched from the tip of the spar to his waist and continued four inches wide down his legs to where it anchored at the little toe. By four o'clock that afternoon, I was feeding them solid food and, with the spars closed, they were holding little cups and drinking water from them in a most humanlike way. He said, "'Ello, 'ello." I would invent a euphonious set of words to match the Basic English vocabulary and teach it to them as their language. I would teach them legends: that they had come from the stars, that they had subsequently watched the first red men and then the first white men enter these hills. There would be volpla colonies all up and down the Coast before anyone suspected.

 She has been giving him alcohol, which could have been adding to the talkativeness  She is talking more than he is, so the effort is misplaced  He is usually fairly quiet, and this is unusual behavior for him  He is being supportive of his friend for once and should be encouraged
