If you've got a Gamecube then most of the Nintendo games are great two-player fodder, especially Mario Kart (although she's easy to beat.. heh) - but the Mario Party games are good, and Donkey Konga.
On the PC we play far less games, but Fahrenheit is the current fav.
Oh and on the PS2 I recently bought Taito Legends, more for me really, but it has this game on it called Plump Pop which I swear is the funniest thing we've played in a long time! Both players at once, it is superb - we finished the entire thing in one sitting and laughed for nearly all of it. Great stuff
