GO GROUNDLINGS SWIMSUIT EDITION Drawing on a variety of current themes and issues, the Groundlings shine in their newest show, which, following a Groundlings tradition, has nothing to do with the title. Featuring strong comedic writing, the sketches also incorporate music, including "Womanisms," a song about (f)e-mails women forward to each other; "Rockstar," in which a man is trying to write a jingle for an energy drink; and "Trade School Musical," a parody of trade-school commercials set to familiar pop tunes. While there is nary a flop in the bunch, the highlights of the show, "Love" and "Taste Test," both feature Melissa McCarthy, who leaves the audience roaring with laughter. McCarthy is never afraid to make a fool of herself, and her uproarious style, reminiscent of the late Chris Farley, makes it impossible for us to keep a straight face. Jeremy Rowley, Alex Staggs, Annie Sertich and Kevin Kirkpatrick also give memorable performances. Director Karen Maruyama, who orchestrates a couple of improv sketches during the show, keeps the evening moving at a brisk pace, never letting the audience settle into apathy. She is aided by the always-lively Groundlings band, which makes transitions entertaining with musical selections that match the themes of the sketches. Groundlings Theatre, 7307 Melrose Ave., W. Hlywd.; Fri., 8 p.m.; Sat., 8 & 10 p.m.; thru April 19. (323) 934-4747. (Mayank Keshaviah)
