Peanut Butter and Pregnancy?

I know, interesting combination. Not two things that you would normally think about at the same time. Yet, when I was at Casa Alba orphanage yesterday it came up constantly.
My good friends are here right now (we met as they began coming here to serve on their summer vacations and Christmas breaks...) and they brought me a book that shows you how to make crazy stuff out of food. So, I decided to do something from the book yesterday with Pink Room and Green Room. We made cows - and they looked awesome!
The face of the cow was covered in Peanut Butter. All of the Romanian staff went "what is that incredible smell?" (Peanut Butter isn't sold here, and even if you randomly find it on a shelf it isn't eaten at all. Their equivalent of Peanut Butter is either Pork, Chicken or Vegetable Pate that they spread on bread in the same fashion.)
I said that it was Peanut Butter..."would you like to try some?"

"No, I'm not pregnant."

Huh?

The next staff person - same thing.

The next staff - SAME ANSWER.

I had told them that it was high in protein, and yes, that fat content is high as well....but if you don't eat a lot of it then it's not so bad for you. And, HELLO, it tastes amazing.

"No thank you, I'm not pregnant."

I'm still confused...I really don't want to think that they believe they only need extra protein when they are pregnant or something.

Yeah...not getting this one at all. : )
