Explain xkcd: It's 'cause you're dumb.
Danish is a stick figure character in xkcd. She is very similar in appearance to Megan, but has heavier hair. Personality-wise, she is to Black Hat as Megan is to Cueball.
Like most xkcd characters, her real name is unknown, although Black Hat has called her "my dearest darling danish" as a term of endearment.
