In the story "Of Mice and Men", Lennie tells Crooks about the land. What is his reply at first?

At first Crooks doesn't think much about the dream Lennie and George have. He's very cynical and doesn't believe it can come true. But after talking with Candy and discovering that there's a possibility that the Candy, George and Lennie may have enough money to but a farm, Crooks offers to come and work for nothing.
