Elke Elkberg is Carl's pen pal, female counterpart and love interest in "Carl Wheezer, Boy Genius." She lives on a farm in Sweden, and she came to America to buy llama feed. Carl lied to her that he was a boy genius, Jimmy was his lowly assistant and that he changed Sheen from a monkey to a human to sound more likeable, and Elke told Carl that she was a professional tennis player and a supermodel with the same intention.
