This police officer gets an A+ for his surprise proposal to a kindergarten teacher on her birthday.

Dain Metcalfe, an officer for the Kauai Police Department in Hawaii, flew to Oregon for his girlfriend Auika Muragin's birthday.

With the help of her co-workers at the elementary school, Metcalfe popped the question while Muragin was playing a game with her kindergarten class.

In the touching moment caught on video, Muragin is told she has to turn her back to her students and keep her eyes closed as they prepare the classroom.

When the 26-year-old is told to turn around, she sees Metcalfe down on one knee holding a sign with the words "Ms. Auika Will you Marry Me?"

She immediately bursts into tears as Metcalfe declares his love and asks her to make him the happiest man in the world.

Of course, Muragin says, "Yes!" The happy couple embrace as the classroom applauds.
