If the idea of a group of clowns descending en masse on a restaurant sounds terrifies you down to your bones, you may not want to keep reading: A gang of people dressed as Ronald McDonald recently stormed a Welsh Burger King for a bit of good-natured ribbing.

A witness in the restaurant filmed the group of about 15 or so Ronalds — as well as at least one person dressed as The Hamburglar and one guy in a doctor costume — as they crowded into Burger King on Sept. 23 and started chanting at cashiers.
