. . . Clang boinng clang ding . . . 
The sound echoed around Lancre. 
Grown men, digging in their gardens, flung down their spades and hurried for the safety of their cottages . . . 
 . . . Clang boinnng goinng ding . . . 
Women appeared in doorways and yelled desperately for their children [bad word] in at once . . . 
. . . BANG buggrit Dong boinng . . . 
Shutters thundered shut. Some men, watched by their frightened families, poured water on the fire and tried to stuff sacks up the chimney . . . 
Nanny Ogg lived alone, because she said old people needed their pride and independence. Besides, Jason lived on one side, and he or his wife whatshername could easily be roused by means of a boot applied heavily to the wall, and Shawn lived on the other side and Nanny had got him to fix up a long length of string with some tin cans on it in case his presence was required. But this was only for emergencies, such as when she wanted a cup of tea or felt bored. 
 . . . Bond drat clang . . . 
Nanny Ogg had no bathroom but she did have a tin bath, which normally hung on a nail on the back of the privy. Now she was dragging it indoors. It was almost up the garden, after being bounced off various trees, walls, and garden gnomes on the way. 
Three large black kettles steamed by her fireside. Beside them were half a dozen towels, the loofah, the pumice stone, the soap, the soap for when the first soap got lost, the ladle for fishing spiders out, the [bad word] duck with the prolapsed squeaker, the bunion chisel, the big [bad word] brush, the small [bad word] brush, the [bad word] brush on a stick for difficult crevices, the banjo, the thing with the pipes and spigots that no one ever really knew the purpose of, and a bottle of Klatchian Nights bath essence, one drop of which could crinkle paint. 
 . . . Bong clang slam . . . 
Everyone in Lancre had learned to recognize Nanny's pre-ablutive activities, out of self-defense. 
"But it ain't April!" neighbours told themselves, as they drew the curtains. 
In the house just up the hill from Nanny Ogg's cottage Mrs. Skindle grabbed her husband's arm. 
"The goat's still outside!" 
"Are you mad? I ain't going out there! Not now!" 
"You know what happened last time! It was paralysed all down one side for three days, man, and we couldn't get it down off the roof!" 
Mr. Skindle poked his head out of the door. It had all gone quiet. Too quiet. 
"She's probably pouring the water in," he said. 
"You've got a minute or two," said his wife. "Go on, or we'll be drinking yoghurt for weeks." 
Mr. Skindle took down a halter from behind the door, and crept out to where his goat was tethered near the hedge. It too had learned to recognize the bathtime ritual, and was rigid with apprehension. 
There was no point in trying to drag it. Eventually he picked it up bodily. 
There was a distant but insistent sloshing noise, and the bonging sound of a floating pumice stone bouncing on the side of a tin bath. 
Mr. Skindle started [bad word]  
Then there was the distant tinkle of a banjo being tuned. 
The world held its breath. 
Then it came, like a tornado sweeping across a prairie. 
"AAaaaaeeeeeee-" 
Three flowerpots outside the door cracked, one after the other. Shrapnel whizzed past Mr. Skindle's ear. 
"-wizzaaardsah staaafff has a knobontheend, knobontheend-" 
He threw the goat through the doorway and leapt after it. His wife was waiting, and slammed the door shut behind him. 
The whole family, including the goat, got under the table. 
It wasn't that Nanny Ogg sang badly. It was just that she could hit notes which, when amplified by a tin bath half full of water, ceased to be sound and became some sort of invasive presence. 
There had been plenty of singers whose high notes could smash a glass, but Nanny's high could clean it
