Dads rock (mine included).
So much so that it's a wonder why there's only one day devoted to their awesomeness (and it's coming up), so you better make it count!
That being said, if I had a dollar for every time my dad told me how much he loves his leather key cap, I'd have enough money to buy his father's day gift next year.
Get him a gift he deserves (and will actually use).
