My sister and I often make donations in my dad's honor as a gift, since he usually doesn't want anything. If you're in the same boat and want to do good in the world, make a microloan donation to Kiva in honor of your dad. By doing so, you'll help someone else - perhaps even another father - succeed and support a family. All repayments are funneled back into your account so you can lend them to someone else after. Look for the heart on the donation description before you check out so you can click it and dedicate your loan to your favorite Dad, including a special message about why you chose that loan.
