groundhog

Harold Ramis made a passel of great comedies, but he never made one better than Groundhog Day.

A groundhog sat up on a log and whistled, too, after a manner of his own.

The groundhog knows enough to go into his hole when the snow begins to fly, and to stay there until the sun thaws him out again.

Alan would none of it; he was off to his woodchuck or groundhog.

He focused his own gaze upon the commissioner's eye as intently as he would have watched a groundhog hole in the hills.

It was with him, however, "a groundhog case," as we used to call such imperative occasions.
