If you haven't been to a Dockyard Derby Dames bout yet, or any sort of roller derby, from the national champion Oly Rollers to the upstart Toxic 253, you officially suck. There, we said it. The good news is you can redeem yourself Saturday as the Derby Dames return to the Foss Waterway Seaport for the third bout of the season. Watch the Hellbound Homewreckers face off against Femme Fiana and the Marauding Mollys take on the Trampires. It's about time you caught on.

[Foss Waterway Seaport, 6 p.m., $10, $15 at the door, 705 Dock St., Tacoma]
