“Early on, Zinkoff's mother impressed upon her son the etiquette of throwing up: That is, do not throw up at random, but throw up into something, preferably a toilet or bucket. Since toilets or buckets are not always handy, Zinkoff has learned to reach for the nearest container. Thus, at one time or another he has thrown up into soup bowls, flowerpots, wastebaskets, trash bins, shopping bags, winter boots, kitchen sinks and, once, a clown's hat. But never his father's mailbag.”
