Holiday Gift-Giving (and receiving)

The Smartest Man Alive: What do you want for Christmas?

Me: I don't know. Um, um, um...I don't know.

The Smartest Man Alive: I'm going shopping tonight, so I need to know.

Me: Well, um, you know what I like.

(after about a half an hour of more of the same, which I will not bore you with...)

The Smartest Man Alive: You'll get nothing and like it!

Well. Apparently, I need some ideas. I really don't want us to spend too much on each other this year. We have a kid now. There's a recession. You know the drill. What should I ask for?

Also, I haven't done much shopping myself, so: What should I get The Smartest Man Alive?

Clearly it's a bit late in the game, so I need gifts that can be purchased in a store. That's not too much to ask, is it?
