According to the Dragula's license plate, Grandpa was born in 1367.
When Herman asks Mr. Baylor what kind of race car he has, Baylor replies, "A rail." Herman then says, "A rail? Oh yes, one of my wife's relatives was once run out of town on one." Being "run out of town on a rail" refers to a punishment most prevalent in the United States in the 18th and 19th centuries in which an offender was made to straddle a fence rail held on the shoulders of two or more bearers. The subject was then paraded around town or taken to the city limits and dumped by the roadside.
First in-episode appearance of the "Drag-u-la" car.
