Trolls will be fed to the pigeons.
Brits call sports "sport" and math "maths." We don't know why, but Jimmy Carr thinks it's hilarious that Americans don't go along with it. Trolls will be hoisted on their own petard. then we'll bury the petard in the yard, put it under guard, and then do something else that rhymes with yard. Which, of course, the Brits call a garden.
