Bring Me Another Shrubbery

An elderly couple in England were caught recently with a shrubbery in their garden, which, unbeknownst to them, was marijuana! They bought it as a seedling at a "car boot sale", which is kinda like a rummage sale in the United States. They claimed that they had no idea it was cannabis, and the police did not press charges. But they do need another shrubbery.
