"like the obstructive sheep in Alice Through the Looking-Glass"

 Through the Looking-Glass and What Alice Found There (often called simply Alice Through the Looking-Glass), is the 1871 sequel to Alice's Adventures in Wonderland, both by English author Lewis Carroll (Charles Lutwidge Dodgson). At one point in this fantastical tale, Alice meets the White Queen, who then turns into a sheep in charge of a shop. The sheep confuses Alice with seemingly nonsensical questions and statements, once again getting her nowhere!
