In an elaborate scheme to both propose to his now-fiancée and give the kids extra recess, Justin Coats (A.K.A. DJ J-Krisp) enlisted the help of Mandy Toombs' students to make his proposal special. Justin got both teachers and students at South Boston Elementary School to participate in a proposal video. Then he arranged for Mandy watch it in front of her classroom, and had some students bring in a banner reading, "Ms. Toombs, Will You Be Mrs. Coats?" The fact that the kids were in on the proposal will make it easier for her to adjust to the name change.
