Terry Pratchett said this quote

Rincewind sighed, and padded around the base of the tower toward the Library.Towards where the Library had been. There was the arch of the doorway, and most of the walls were still standing, but a lot of the roof had fallen in and everything was blackened by soot.Rincewind stood and stared for a long time. Then he dropped the carpet and ran, stumbling and sliding through the rubble that half-blocked the doorway. The stones were still warm underfoot. Here and there the wreckage of bookcase still smouldered. Anyone watching would have seen Rincewind dart backward and forward across the shimmering heaps, scrabbling desperately among them, throwing aside charred furniture, pulling aside lumps of fallen roof with less than superhuman strength. They would have seen him pause once or twice to get his breath back, then dive in again, cutting his hands on shards of half molten glass from the dome of the roof. They would have noticed that he seemed to be sobbing.Eventually his questing fingers touched something warm and soft. The frantic wizard heaved a charred roof beam aside, scrabbled through a drift of fallen tiles and peered down. There, half squashed by the beam and baked brown by the fire, was a large bunch of overripe, squashy bananas. He picked one up, very carefully, and sat and watched it for some time until the end fell off.Then he ate it.
