The license plate on Mr. Black's car is "J03M4M4", read as "Joe Mama".
The Lord of the Rings was an analogy for WWI, not WWII as Stan states. J.R.R. Tolkien arrived in the British Army during the war and based much of The Hobbit and The Lord of the Rings of his experience.
This episode did not translate well to British audiences. The words "token" and "Tolkien" are said in a distinct way in British English. They would not be confused.
