The unbudgeable curmudgeon / Matthew Burgess ; illustrated by Fiona Woodcock.

"Have you ever seen a curmudgeon that looks like your brother, but is in such a bad mood you hardly recognize him? You can try all the peanut butter sandwiches and brownies you have, but he is not moving. Nothing works, especially nudging, and he just makes you so grumpy that eventually you have no choice but to fight back--and then... Have you ever become a curmudgeon that just won't budge?"--Amazon.
