There are a few gags in the show which are for the enjoyment of hardcore vampire fans. The following exchange comes to mind:
MARIA: You miss your land very much.Get it? Get it? Meh, what do you know from funny, go look it up.
PORLOCK: Truly ... though I have brought some of it with me.
However, the biggest inside joke I put in the script arrived thanks to GLTF homeboy and benefactor Tom Hanks who gave an interview with Scott SImon back in October which recently aired on PBS. After being asked about high school, he shares that the first play he saw his friends in school do was Dracula, and how the teacher-director decided to adapt the text to fit the fact that he cast an Asian-American student to play the part of Van Helsing (see clip.)
