Limey Charles Worcestershire Sauce is a sauce seen in the Season One episode, "Pinkeye".
Background
In "Pinkeye", Kenny dies again and is taken to Morgue. At the Morgue the Mortician and his assistant are "working" on Kenny. The Mortician's assistant whips out a hot dog and some of Limey Charles Worcestershire Sauce and digs in. While Kenny is "draining", the sauce is mixed with embalming fluid and turns Kenny into a zombie. Kenny then infects almost everybody in town. Limey Charles must have known that mixing embalming with their sauce causes zombies as it says not to mix the sauce with embalming fluid.
