Play something easy with a lot of lights and explosions.
Something like Halo (single mode), Grand Theft Auto, Marvel vs Capcom (or any other fast-paced 2d fighter), or Dynasty Warriors. I've never played Shinobi, but I imagine it'd be good. Or maybe just whip out an old game that can be beaten pretty easily in an hour or so, like Streets of Rage.
I like Einhander, but that's moderately rare and can get pretty tough
