Bah Humbug!!!

So here it is, December 15th, and i'm still not done Christmas shopping. I've finished for most people, but there are just a few people that i am having such a hard time shopping for! The hardest of them all is my dad. What in the world can you buy him?! He has pretty much everything, and i know this for a fact because I was the one who bought it all for him! He really doesn't need anything. He has all the TVs, IPod touches, sneakers, hoodies, computers...everything...that you could need! I am at such a loss this year. And i know how much money he spends on us, so i can't just show up with a gift card and be like "Here's your present, Merry Christmas!" Any ideas on what to get the hardest man in the world to buy for would be greatly appreciated. Greatly.
