Instructional aid Melissa Sagaser, left, guides Horizon Middle School student Jacob Vetter's hand to squish a whipped cream pie to the face of his special education teacher, Missy Moritz, at a school assembly on Thursday, March 28, 2013. The messy activity helped raise funds for the upcoming Great American Bike Race charity event held April 13 in Bismarck. Jacob, who has cerebral palsy, is a former GABR star. To help raise money for the school's teacher riding team at this year's Great American Bike Race, students donated $1 for a chance to throw a pie at a teacher. The effort raised $750 and 35 students were rewarded with throwing whipped cream at 19 teachers.
