Louis Wu over at HBO pointed out an item over in their forum-- apprently Uriel spotted a mention of Halo and the Xbox over in the column by Dom, one of the MegaTokyo artists, in today's strip.
Dom calls the little aliens in Halo the most fun bastards to shoot (we assume he means grunts). But more telling is his experience with the Xbox controller:
There has seriously been a collective brain fart by the Xbox guys with this monstrosity. The testers for the controller must've been Manute Bol and a rhesus monkey with elephantiasis. There's no other explanation for something this bad.
I'm guessing that means he doesn't like it.
