T brought home the one of funniest, most random things the other day. It's a video game called Katamari Damacy. Basically, you roll a ball around and you pick things up with it. It's one of those things that is difficult to do justice with words. Here's a good description from Wikipedia. Jed also blogged about it a couple of months ago.
I watch T play it and laugh my head off, mostly when he starts picking up animals, people, and improbably large things like cars. I laugh less when I'm play, although I still encounter the occasional giggle fit, because it can be so much trouble to get the damn ball to go exactly where I want it to -- I tend to prefer games that don't tax my hand-eye coordination too much. There's a two player mode; we played with it a bit, and T kicked my ass pretty thoroughly. It was still fun, though.
