TWO LIPS: The weather looks to be gorgeous this weekend, and what better place to enjoy it than the West Side Community Garden Tulip Festival? More than 30 varieties of tulips put on nature's floorshow, and if that's not enough, there'll be free home-baked cookies and lemonade. Sat., 1-4PM.
LYNCHED: David Lynch's Eraserhead (1977) screens at midnight at the IFC, because if there's ever a time to sit in the dark watching a surrealist horror nightmare involving adultery, fake chickens spewing blood, and a baby with a pig snout, it's at 12AM. Fri., Sat.
CRAWS FOR CELEBRATION: Other than tulips, know what this sunshine calls for? An afternoon spent outside, getting elbow-deep in crawfish and corn, and washing it all down with beer. Thank goodness Park Slope's Flatbush Farm, with its patio Crawfish Boil, has you covered. Sun. 4PM-7PM.
PARK IT: The Central Park Conservancy throws its annual Earth Day bash on Sunday, and it's a doozy: dozens of activities and installations will unfold, from human-bicycle-powered live music to free treats from Red Jacket Orchards to a stroll of the Park's "quiet zones." Plus, everybody's favorite: Worm-composting demonstrations! Sun., 12-4 PM.
SIKH DAY: Those 50,000 be-turbanned folks parading down Broadway? That's the Sikh Day Parade! This traditional harvest festival starts at 41st Street and ends at 24th Street, where a massive Indian feast will be served to all 50,000 -- and you -- for free. 11:30AM-5PM.
