From chapter five of a Doctor Who fic titled "Bubbles" (link is to the first chapter, because this is just the shiniest gem in a fic made from comedy gold):
Quote:"It's like touching butterfly wings," the woman said dreamily, hugging one of the new dresses.
"I think it's been a bit much for her," muttered Francine.
"Butterflies covered in cornflour," Sharon continued happily, her eyes glassy.
"Mind you, I know how she feels," Francine added, a smirk pulling at her lips.
"Tempura butterflies!" Sharon crooned.
Tish was going a very interesting shade trying to stop herself laughing. "Come on," she managed. "Home." She waved at Martha and winked before pulling Francine, protesting, from the shop.
