Thelma: J.J where'd you get stamps to mail a letter?
JJ: I don't need no money for stamps! The last six letters I painted em on.
Question: According to the credits, the smallest of the three Satan Knights that come over to get JJ is nicknamed "Sweet Pea." However this name is never mentioned by anyone in this episode. The other two are mentioned (Mad Dog and Neck Bone). Why would the credits use a name not used?
