I need help coming up with Stocking Stuffers for my husband!!!?

Each year I normally fill his stocking with candy, gum, a toothbrush & toothpaste (santa cares about dental hygiene you know) and little odds and ends I'd find cheap. But this year I'd like to stuff that thing full of cool stuff! Any ideas? He's 31, a gamer, we've got 2 kids and 1 on the way, and he works really hard to take care of us. I'd appreciate any help!

What about you in the stockings?! lol There's loads of cool little gadget things in the stores each Christmas. Last year I got my son a laser light keyring, a bottle opener that when used a light would flash, a ball that would have different sayings in it, some racing grannies with their zimmer frames, a pen that recorded voices and played it back, either normally, or in different ones, a spy kit, a ball that vibrated and you could spin it in your hand and developed your muscles, a tie that had a flashing light and could play Jingle Bells, some character socks, a multi-function tool thing, etc! Some of those I got from stores, some from the pound shop and some from sites online that I googled! I hope this helps!
