Dobson High school principal Matthew Gehrman shakes each graduates hand during the Dobson High school commencement ceremony, Thursday, May 28, 2010 in Mesa. Some students gave Gehrman a dime when shaking his hand, “I didn’t know they were going to do this. It was a last-minute thing with the Class of 2010. I ended up with 246 dimes. About every other kids was giving me a dime.” Gehrman said, laughing.
