I saw this the other day, and found it both funny and thought-provoking.

"Hello! Do you have a minute to talk about Dracula?"
"No– wait, Dracula?"
"Yes!"
"You’re vampires?"
"Yes. We have pamphlets."
"Vampires have missionaries?"
"Where else would new vampires come from?"
"I assumed you bit people."
"There are many hurtful stereotypes. May we come in?"
