I couldn’t help but think of Shakespeare’s magnificent seven ages of man speech from “Hamlet” while taking in “Grumpy Old Men,” Surflight’s current mainstage musical.

Babies come into the world “mewling and puking in the nurse’s arms.” Men then, in turn, become a whining schoolboy, a lover, a soldier and a justice before hitting their later years, when it turns out they were smart when they kept their old hose from their youth because they once again fit thanks to their shrunken shanks.
