(SLURPIN') At last year's event, they ate 30,000 oysters. Sounds heavenly, doesn't it? Plus: A shucking contest, a Celebrity Slurp-Off, and other oddities—and it's a benefit for the clean-water crew at Puget Soundkeeper Alliance. But if you can't shell out 85 freaking dollars for a good cause, pick up some beer and bivalves and have a slurping contest of your very own. (Anthony's HomePort at Shilshole Bay, 6135 Seaview Ave W, 297-7002. 3–9 pm, $85. Or your place. Whichever.)
