A 4-year-old boy who just had surgery showed his gratitude by raising money for Stony Brook Hospital.

Bobby Volk says the hospital and kids need "stuff," so he asked his mom to bake cupcakes and cookies for a bake sale.

Bobby put the baked goods in his wagon and went door to door asking for donations at his mom's job.

All together he collected about $300 for the hospital.

Bobby now says he thinks he wants to be a baker when he grows up.
