What are your best memories of a Dreamcast multiplayer session?

Back when the DC was a new console i played most of the time for myself (Shenmue, Grandia 2, PSO, etc). It was later at university when I got more into (couch-)multiplayer. My dearest memory is playing Chu Chu Rocket with two of my friends while listening to Blood Brothers - really loud. This game gives me heart attacks and freaks me out. Blood brothers was just the right soundtrack to it. Plus beer and NicNacs, perfect night. (Later on we popped in Mario Kart Double Dash btw. Blood Brothers fits that really well, too.)
