The Mouse That Roared

From Edna:

My brother had a white mouse that invented an alternative to endlessly turning the exercise wheel. This mouse would get it spinning fast, jump off, and grap onto the outside of the wheel. He rode it up to the top, where he would wedge himself under the glass ceiling with a squeek.

I don't know what he got out of it, but he did it often enough that my brother named him "Stupid." In retrospect, he seems like an adventurous pioneer mouse whose experiments just didn't pan out.
