Lotsa Words

Translated, in the last panel, from behind Moe & Brennan, is:

Because, Brennan, the cells in your body are trying to tell your cerebellum that you are not prepared to know where your mother is yet. Now, if you are not fit to know where Mom is, we must not tell you until you are ready to know. Therefore, your mother and I have put up signs so you can get ready, and, at the same time, look for her. This reason contains some secrets that I have not told you. This concludes my reason.

I had to use a thesaurus to get some of the words longer to make it funnier. For example, I put "cerebellum" instead of "brain." What do you think the secret is?
