What to a get a guy who has everything for christmas?

okay, my husband is the hardest man to buy for, he literally has everything. Playstation/blue ray player thingie :) blue ray player for tv upstairs. surround sound, 2 flatscreen tvs. he has the macbook air, and a macbook pro for work. he has the iphone, he has a regular phone, he has an ipod, and ipod touch, and an ipod nano, he has a car speed detection thingie, and a gps unit, he has a poker table, and a workout set, he doesn't wear jewlery or watches, and he has clothes, he likes food, but not big on it as being a gift, we already have a grill, and a whole grill set. he has cologne, and he has movies, and games...so my question is..what the hell do I get him? he has everything! I thought about getting him the polaroid to go, or on the go or whatever it is, but I'm not sure he'll be too impressed..any ideas? I'm looking no more than 300 dollars. Thanks!
