Tortoise worming event sounds way worse than it actually is

A roadside sign for 'All Creatures' advertising a tortoise worming event for £5.00 on Saturday the 12th of July from 1:30-3:30pm. The sign is positioned in an overgrown grassy area with trees in the background, appearing to be a legitimate veterinary or pet care service announcement with an unintentionally humorous name.
