What should i get my dad for father's day?

I'm 15 and as you all know Father's day is comin up and I have nooo idea what to get my dad. My dad is 67 years old ( ya I know old right?) And I don't want to get him tools or fishin gear or anything like that cause he has all that already. I want to get something that would be helpful and something special that doesn't cost like 50 bucks or more.... so anyone have any ideas?
