Answer: Boris Karloff was a real actor who is mostly famous for playing Frankenstein and The Mummy in the 1930's. He had many other roles in classic horror films of that era.The young host is naming himself after the actor.

The answer is true, but the question asked about Boris Karloff Jr, who didn't exist. Boris Karloff had only one child, a daughter named Sarah. As for Binx, he was angry about them opening the book and even states that nothing good could ever come from it. He was not only cautious about the sisters (and any concern he had there was valid), but he also knew that everything in the book was evil and didn't want to risk other issues it causes whether the sisters were involved or not.
