(PARTY) According to Don Leonardo, a handsome scoundrel with a ferocious left hook, "Sean Spits and I will have a fistfight to the death. If he survives, the Spits will play." I hope Sean has been training, because there are few punk pleasures greater than a daytime Spits show on a sunny Saturday. The beer will be astonishingly cheap, the barbecue will be smokin', and Mamma Casserole will be on the decks, so consider your plans made. (Funhouse, 206 Fifth Ave N, 374-8400. 4 pm, $6, 21+.)
