 1749, John Cleland, Fanny Hill: Memoirs of a Woman of Pleasure, Part 3
 Mr. H …, whom no distinctions of that sort seemed to disturb, scarce gave himself or me breathing time from the last encounter, but, as if he had task'd himself to prove that the appearances of his vigour were not signs hung out in vain, in a few minutes he was in a condition for renewing the onset
 2012 August 5, Nathan Rabin, “TV: Review: THE SIMPSONS (CLASSIC): “I Love Lisa” (season 4, episode 15; originally aired 02/11/1993)”, in (Please provide the title of the work):
 Valentine’s Day means different things for different people. For Homer, it means forking over a hundred dollars for a dusty box of chocolates at the KwikEMart after characteristically forgetting the holiday yet again. For Ned, it’s another opportunity to prove his love for his wife. Most germane to the episode, for Lisa, Valentine’s Day means being the only person in her entire class to give Ralph a Valentine after noticing him looking crestfallen and alone at his desk.

 WikiLeaks did not cause these uprisings but it certainly informed them. The dispatches revealed details of corruption and kleptocracy that many Tunisians suspected, but could not prove, and would cite as they took to the streets. They also exposed the blatant discrepancy between the west's professed values and actual foreign policies.
 I will prove that my method is more effective than yours.

 2012 May 5, Phil McNulty, “Chelsea 21 Liverpool”, in BBC Sport:
 He met Luis Suarez's cross at the far post, only for Chelsea keeper Petr Cech to show brilliant reflexes to deflect his header on to the bar. Carroll turned away to lead Liverpool's insistent protests that the ball had crossed the line but referee Phil Dowd and assistant referee Andrew Garratt waved play on, with even a succession of replays proving inconclusive.
