t-shirt suggestions

I need some graduation ideas for our Kindergarten Graduation t-shirt this year. I went to the shirt place today to get a quote and she asked me if I had any idea of what we wanted. I have no idea. Our mascot is a Hornet and "Buzzing out of Kindergarten" came to my mind immediately, but I have no idea what clip art to put on the front. I kinda like the idea of little boys and girls holding hands, but I don't have a theme or saying. Do any of you ladies have any suggestions for me?
