George and Lennie

A three-day weekend now comes to an end, and I'm sure most of us has already read the beginning (0-30 pages at least) of "Of Mice and Men." Well, we're supposed to be done with the book by our next meeting. I'm interested to know what my fellow classmates think of the two main characters, George and Lennie. (Trying to get another conversation up and going)

Question

How does the title of this novella relate to Robert Burns' poem, "To A Mouse?"
